MuMu Emulator Install Errors and Startup Failure Troubleshooting
Most install and startup errors are traceable: VT off, software conflicts, antivirus blocking, not enough disk space. This article maps common errors to specific fixes, so just work through the checklist item by item.
MuMu emulator says it needs VT virtualization enabled during install, how do I turn it on in BIOS?
VT (virtualization) is a requirement for MuMu to run. To enable it: press the BIOS entry key at boot (commonly Del, F2, F10, depending on the motherboard) to enter BIOS, find the Intel VT-x or AMD SVM (virtualization technology) item in the CPU or Advanced menu, set it to Enabled, then save, exit and restart.
On Windows 11 you also need to turn off Core Isolation and Hyper-V and VBS. Note that Surface devices do not support VT and cannot run it (BIOS keys and option names vary by motherboard, so verify yourself).
Installing MuMu emulator gives an error about a Hyper-V conflict, how do I solve it?
MuMu 12 conflicts with Hyper-V and VBS and Core Isolation, which is very common after a Windows 11 (especially 24H2) upgrade.
Official fix: turn off Windows Core Isolation, disable Hyper-V and VBS, and at the same time make sure VT virtualization is enabled in BIOS. After completing these three adjustments, restart the computer and then start the emulator for it to run normally.
Most install errors can be solved by enabling VT, closing conflicting software, and leaving enough space.
MuMu emulator install says it conflicts with the antivirus on my computer, should I turn it off?
We recommend temporarily turning off antivirus and protection software (Tencent PC Manager, 360, Windows Defender and so on) before installing, otherwise it easily blocks emulator processes (such as the NemuDrv driver) and the install fails or stalls.
After installing you can turn antivirus back on and add the blocked MuMu-related processes to the allowlist. The genuine MuMu build has been scanned by multiple tools with no malware; virus reports are mostly false blocks by antivirus or non-official installers, so just download from the official site.
After downloading MuMu emulator, Windows Defender reports a virus, is it a false positive and can I trust it?
The genuine MuMu downloaded from this site is mostly a false positive. Multiple independent checks (lo4d virus and malware test, VirusTotal with no triggers) and community self-checks found no malware in the genuine build.
NetEase has also stated officially that the flashing or floating ad in the top-right of the emulator is not officially embedded but the work of rogue ad software on the user computer, and recommends a full scan and removal on the computer. During install antivirus often blocks the emulator driver (such as NemuDrv) and the install fails, so you can temporarily turn off protection and allow it. But the premise is downloading from this site playermumu.com; third-party cracked packages really can be repacked with malware, and those cannot be trusted.
After downloading MuMu emulator the installer says the file is damaged or verification failed, what do I do?
First confirm you downloaded from this site playermumu.com, since packages from third-party sites are easily repacked and fail verification.
Next, downloads are often incomplete because the overseas network drops, so change the DNS (114.114.114.114 and so on), run ipconfig /flushdns, then download again, or switch to a wired network and retry. Before installing close antivirus and protection software (PC Manager, 360, Defender), which may block or corrupt the install file. Note that the official online installer itself is only tens of MB, while the full image reaches the GB level, so do not be confused by the size. If it still fails, download the full package again.
Installing MuMu emulator gives an error code starting with 0x, what does it mean and how do I fix it?
When MuMu emulator install gives an error code starting with 0x, the source material does not map to a specific 0x error code. These install errors are mostly related to virtualization, drivers or protection software blocking, so handle them in the official troubleshooting order: 1) enable VT in BIOS;
2) use Driver Genius to update the graphics and audio drivers to the latest; 3) close Tencent Manager, 360 and the firewall, and allow blocked processes (such as NemuDrv); 4) go to the settings center, switch the graphics rendering mode, then restart; 5) uninstall and reinstall, or run networkReset.bat as system administrator to reset the network. Windows 11 users additionally need to turn off Core Isolation and Hyper-V and VBS.
MuMu emulator will not open after installing, what causes the black screen and crash?
When MuMu emulator will not open after installing and shows a black screen and crash, follow the official five-step check: 1) enable VT in BIOS (a requirement);
2) use a driver tool to update the graphics and audio drivers to the latest; 3) close Tencent Manager, 360 and the Windows firewall, and allow processes blocked by antivirus (such as NemuDrv); 4) go to Settings Center and Advanced Settings, switch to another graphics rendering mode, then restart; 5) uninstall and reinstall, or run networkReset.bat as administrator to reset the network. On Windows 11 you also need to turn off Core Isolation and Hyper-V and VBS.
MuMu emulator install keeps stalling at a certain progress, where is the problem?
When MuMu emulator install keeps stalling at a certain progress, the most common causes are being blocked by antivirus or VT not being on. Troubleshoot in the official way: 1) first enable VT (virtualization) in BIOS, which is a requirement;
2) before installing, close protection software such as Tencent PC Manager, 360 and Windows Defender, and allow blocked processes (such as the NemuDrv driver); 3) right-click and run the installer as administrator; 4) install to an SSD and choose a non-system drive (D or E). If it stalls at the startup stage, you can also switch the graphics rendering mode in Settings Center and Advanced Settings, then restart, or uninstall and reinstall.
I am installing MuMu emulator in Malaysia, can I choose Chinese as the install language?
Yes. MuMu supports 13 localized languages and covers more than 200 countries and regions; Chinese (including Traditional) is one of the options, and both the install and interface can be in Chinese.
We recommend downloading directly from playermumu.com, then choosing Chinese during installation or in the settings center after entering; it has Google Play built in and is well suited for playing multi-region mobile games in Malaysia. Remember to close antivirus and protection software before installing, and install to a non-system drive.
MuMu emulator install tutorial, what are the full first-time steps?
Full steps: 1) download the installer from the official domain of this site (playermumu.com); 2) before installing, enable VT virtualization in BIOS and close protection software such as Tencent Manager, 360 and Defender to avoid interception;
3) run the installer, click custom install to change the path, ideally install to a non-system drive on an SSD (D or E), and right-click to run as administrator if permissions are insufficient; 4) once installed, start the emulator; the first launch downloads the Android system image, so wait patiently; 5) once at the desktop it is ready to use, and the MuMu or NetEase account is not mandatory, so you can play without logging in.
MuMu emulator keeps popping up UAC prompts during install, should I run as administrator?
When MuMu emulator keeps popping up UAC during install, we recommend running it as system administrator. Installing the emulator loads drivers (such as NemuDrv) and writes system settings, and with insufficient permissions the install easily fails or stalls, so when you see a UAC prompt allow it, or simply right-click and run the installer as system administrator.
At the same time, before installing, close antivirus and protection software (Tencent Manager, 360, Defender) to keep them from blocking emulator processes; during install you can change the path in custom install, and installing to a solid-state, non-system drive is more stable.
Below are real questions and answers about install errors and startup failures, grouped by error type for targeted troubleshooting.
My company computer has no administrator rights, can I run MuMu as a portable build without installing?
It is very hard. The MuMu install process installs system-level drivers (such as NemuDrv), and with insufficient permissions the official requirement is to right-click and run as administrator, and VT (virtualization) must be enabled in BIOS to start, all of which need administrator rights, and there is no official portable no-install build. A controlled company computer usually cannot install it, and it is not advisable to install on a company device anyway. The workable approach is to use a personal computer that has administrator rights and VT enabled. (A portable no-install build is not covered by the source material, marked as verify yourself.)
Can MuMu emulator be installed on the D drive? Can the install path be changed to avoid the C drive?
MuMu emulator can be installed on the D drive. During install click Custom Install in the installer, change the path, and choose a non-system drive such as D or E to avoid filling up the C drive. Both official and community sources recommend installing to an SSD to improve performance. Note that the install drive needs at least 2GB free and the system drive at least 1.5GB free; if permissions are insufficient, right-click and run the installer as administrator.
MuMu emulator says disk space is insufficient at the end of install, how many GB do I need to keep free?
When MuMu emulator says disk space is insufficient at the end of install, per the international official system requirements the install drive needs at least 2GB free and the system drive at least 1.5GB free; some Chinese pages write 4GB, which is a difference between game bases, and for large games in practice it is more stable to reserve more. We recommend installing to an SSD and choosing a non-system drive (D or E) to avoid filling up the C drive. You can click Custom Install in the installer to change the path and choose a drive. If permissions are insufficient, right-click and run as administrator.
After downloading and installing MuMu emulator the first boot keeps spinning at initialize, how long is normal?
When the first boot of MuMu emulator keeps spinning at initialize, the first initialization has to unpack the Android image, so being slower than usual is normal, but if it stalls for a long time (commonly at 99 percent) it is mostly a configuration issue. Follow the official five-step check: 1) enable VT in BIOS (a requirement); 2) update the graphics and audio drivers to the latest; 3) close Tencent Manager, 360 and the firewall and allow blocked processes (such as NemuDrv); 4) go to Settings Center and Advanced Settings, switch to another graphics rendering mode, then restart; 5) uninstall and reinstall, or run networkReset.bat as administrator to reset the network. Windows 11 24H2 users also need to turn off Core Isolation and disable Hyper-V and VBS. The source material does not give a specific normal duration, so verify yourself.
After installing MuMu emulator I cannot log into Google Play, how do I install the Google framework overseas?
When you cannot log into Google Play after installing MuMu emulator, the Google account inside the emulator belongs to the built-in Android system, and before logging in you must first install Google services, and KK Google Assistant must be in Acceleration Mode (that is, a circumvention tool or proxy is needed), otherwise it will surely fail. The domestic build requires going into System Apps and KK Google Assistant to manually install the Google suite. If it is installed but login is still abnormal, follow the official three-step fix: 1) in the top-right [+] of KK Google Assistant choose One-Click Uninstall to remove the old suite; 2) go to menu [three], Settings Center, Property Settings, set the phone brand and model both to Default, then restart; 3) after restarting use KK Google Assistant again to reinstall the suite. The international build has Google Play built in, which is easier, but it still needs a proxy.
What is the official MuMu emulator download address? I worry about getting a knockoff bundled with ads
Trust the domain of this site playermumu.com to download; the Tencent Software Center pc.qq.com also has an official distribution page. Chinese users in Southeast Asia and Hong Kong and Taiwan should download from this site playermumu.com first. Be sure to avoid third-party download sites such as 3dmgame and macappbox and any so-called Pro lifetime or cracked versions, as these modified packages may be bundled with ads or repacked. Virus reports or pop-up ads are mostly caused by non-official installers; the genuine build has been checked by multiple parties with no malware.
What is the NetEase MuMu emulator official website address? Is mumu.163.com the real official one?
Yes, MuMu emulator can be downloaded from this site playermumu.com; the Tencent Software Center pc.qq.com also has official distribution. Other download sources are generally very slow overseas, so we recommend downloading directly from this site playermumu.com. As long as you download from this site it is genuine, so do not go to third-party sites or cracked versions to avoid bundled ads and repacking.
How do I download the official genuine MuMu emulator in Hong Kong?
Hong Kong players should download directly from this site playermumu.com, which supports multiple languages and covers regions worldwide, and is much faster overseas than other download sources, since one Hong Kong player measured overseas downloads of game resources as extremely slow (2GB reaching only 20 percent in an hour). When downloading, trust the domain of this site and avoid third-party sites such as 3dmgame and macappbox and cracked versions, to avoid bundled ads or repacking. If downloads are still slow, you can change the DNS, install the UU accelerator, and use a proxy if needed.
Where do Taiwan users download the Traditional Chinese version of MuMu emulator?
Taiwan users should download from this site playermumu.com. The build here supports 13 localized languages and covers more than 200 countries and regions, with languages better suited to Hong Kong and Taiwan users, and faster overseas downloads. When downloading, trust the domain of this site and avoid third-party sites and cracked versions. The source material does not list the specific entry for a standalone Traditional Chinese installer one by one, so whether a separate Traditional Chinese package exists should be verified on this site; after installing you can switch in the emulator language settings.
Can Singapore go directly to the NetEase MuMu official site to download, or is a VPN needed?
In Singapore we recommend downloading directly from this site playermumu.com, which is aimed at overseas users and covers more than 200 countries and regions, and under normal conditions can be accessed and downloaded without a VPN. Other download sources are generally very slow overseas and are not recommended. Downloading the emulator itself and logging into a NetEase account do not need a VPN; only when you want to use Google Play inside the emulator to play overseas games do you need to configure a proxy. If downloads are slow, change the DNS and install the UU accelerator.
The MuMu emulator official site will not open when downloading in Malaysia, what do I do?
First switch to downloading from this site playermumu.com, which is aimed at overseas users and covers more than 200 countries and regions, and is usually easier to open and faster to download. If it still will not open or downloads are extremely slow, the official and community methods are: check and switch the network (WiFi to wired, avoid company or campus network restrictions), change the DNS to 114.114.114.114 or 223.5.5.5 and run ipconfig /flushdns, and install the UU accelerator; if that fails, use a global proxy or VPN (a community method, at your own risk).
Does MuMu emulator have a Traditional Chinese download, or only Simplified?
The build here supports 13 localized languages and covers more than 200 countries and regions, so in language it is friendlier to Hong Kong and Taiwan and overseas Chinese users, not only Simplified. We recommend Hong Kong and Taiwan users download from this site playermumu.com first. However the source material does not specifically confirm whether there is a separately named Traditional Chinese installer, so this should be verified on this site; in most cases it is the same installer with the language switched in settings.
Where do I download the latest MuMu emulator 12? Does the homepage offer 12 or the older build?
Just download from this site playermumu.com. The homepage of this site offers the current main version, MuMu 12 (built on Android 12, supporting 240 fps, 4K, multi-instance), not the older build. Overseas Chinese users get faster and lighter downloads from this site. Trust the domain of this site to download and avoid third-party sites and cracked versions.
How big is the MuMu emulator PC (Windows) installer?
The online installer (downloader) offered on the MuMu emulator official site is itself very small, about tens of MB; what really takes space is the full Android 12 image and game data it has to download, which together reach the GB level (some sources write 4-5GB, which refers to the full content and not the installer itself). Before installing we recommend at least 2GB free on the disk (more is more stable for big games), installing to an SSD on a non-system drive. So the 68MB and the few GB you see are not the same thing, and there is no need to be confused.
Does MuMu emulator have a Mac download? Can Apple computers install it?
There is a Mac version called MuMu Emulator Pro, which needs an Apple Silicon (M-series chip) Apple computer and a matching configuration. Unlike the free model of the Windows build, the Mac build uses a 7-day free trial plus a paid subscription on expiry, priced at 18 yuan for 30 days, 50 yuan for 90 days, and 178 yuan for 365 days (subject to the in-app live quote). In features it is basically aligned with the Windows build (multi-instance, key mapping, recording, 240 fps, virtual location). You can download it from the NetEase official site or as Handheld MuMu in the Mac App Store.
I cannot download MuMu emulator overseas and it keeps failing to connect to the server, why?
It is mostly because of an overseas-unfriendly download node, since overseas access and downloads are often very slow or even fail to connect, and it is not a local bandwidth issue. First switch to downloading from this site playermumu.com (aimed at overseas users, covering more than 200 regions). If it still will not connect, you can switch the network (WiFi to wired, avoid company or campus networks), change the DNS to 114.114.114.114 or 223.5.5.5 and run ipconfig /flushdns; the help center of this site also offers an overseas connection guide, and use a global proxy or VPN if needed (a community method, at your own risk).
Downloading MuMu emulator in Thailand is super slow, is there a way to accelerate overseas?
First download from this site playermumu.com (overseas downloads are generally very slow, and this site is smoother). Then follow the three official tips to speed up: 1) check and switch the network, WiFi to wired, and avoid company or campus network restrictions; 2) install the UU accelerator from the app store, or after logging into a MuMu account use the emulator built-in Acceleration Service (the menu in the top-right of the device, Acceleration Service, choose the game); 3) change the DNS to any of 114.114.114.114 or 223.5.5.5, then run ipconfig /flushdns and restart to retry. If it is still slow, use a global proxy (a community method, at your own risk).
Downloading MuMu emulator in Vietnam stalls at some percentage, how do I solve it?
When the download stalls, first download from this site playermumu.com (other download sources are extremely slow overseas). Then follow the official methods: switch the network (WiFi to wired, avoid company or campus network restrictions), change the DNS to 114.114.114.114 or 223.5.5.5 and run ipconfig /flushdns, install the UU accelerator or use the built-in Acceleration Service. If the emulator startup stalls at 99 percent (not the download stalling), that is a different kind of problem: you need to enable VT in BIOS, turn off antivirus and allow NemuDrv, switch the graphics rendering mode or reinstall. First tell apart whether it is a download stall or a startup stall.
Is a MuMu account ban permanent or time-limited? How long until it is lifted?
First distinguish: a MuMu emulator account ban and a game account ban are two different things. The emulator is compatible with mainstream mobile games for normal play, but some competitive games (such as the officially cited Dream Star) may be banned by the game side when run on an emulator; whether it is banned and for how long is decided by each game maker anti-cheat policy and is unrelated to MuMu itself. When unsure, consult the game official or MuMu customer service QQ 800185404.
MuMu emulator login says it needs security verification and it never passes, what do I do?
When MuMu emulator login says it needs security verification and it never passes, the overseas environment often triggers security verification or fails to receive SMS because the network node is not in mainland China. You can switch to WeChat scan login, which does not rely on SMS, or use a phone number or ID plus password. If it still stalls, first make sure the emulator is updated to version 4.0.10 or above; contact customer service QQ 800185404 for help if needed. If the problem points to the Google account inside the emulator, you need to first install Google services and put KK Google Assistant in Acceleration Mode.
