MuMu Player Troubleshooting
Fixes for the problems people hit most often, in the order worth trying them.
Stuck at loading or very slow startup
- Enable VT (Intel VT-x or AMD SVM) in BIOS/UEFI; see our VT guide.
- Update your graphics driver from the GPU vendor's site.
- Close other virtual machines or heavy programs, then restart the device.
Installation fails or stops partway
- Re-download from the official page; use the offline installer if your network is unstable.
- Check free space on both the install drive and the system drive.
- Temporarily pause third-party antivirus only if the installer came from the official site.
Games lag or stutter
- Lower the frame-rate limit to 60 and step up gradually.
- Give the device fewer than half of your physical CPU cores, as NetEase recommends.
- On dual-GPU laptops, select the dedicated GPU under performance settings.
Game says the device is incompatible
- Try the same game on an Android 15 device if you're on Android 12, or the reverse.
- Update to the latest build; many releases list game-specific fixes.
- Check the release notes for the title by name.
Keyboard controls don't respond
- Press F12 to toggle the key scheme on.
- Make sure the game window has focus.
- Re-import or reset the scheme if it was edited.
Hyper-V or other virtualization conflicts
- MuMu Player X added support for running with Hyper-V enabled in 2022; if you still see conflicts, update to the current build.
- Disable unused virtualization features only if you understand what depends on them (for example WSL2 or Windows Sandbox).
Mac: Android device won't start
- Free up disk space; NetEase notes low storage causes start-up failures and app download errors.
- Empty the Trash and remove unused apps, then retry.
Known Limitations
- No official Linux or ChromeOS build.
- Windows ARM support is in beta.
- Systems that only support 32-bit can't install the Android 64-bit edition.

Troubleshooting FAQs
Short answers to the most common error questions.
Updates & troubleshooting
The newest Windows build listed in the official release notes is V6.8.0, dated September 23, 2026. The macOS edition follows its own version numbering. We last checked on October 30, 2026.
Download the current installer from the official page and run it; the release-notes page also carries a download link for the latest build. Keep your Android devices backed up first if they hold important data. See the download page for version history highlights.
The usual causes are VT being disabled, too many instances for the available RAM, outdated graphics drivers, or a frame-rate setting higher than your hardware can sustain. Our troubleshooting page walks through each fix in order.
Open Device Settings, then Display, then the frame-rate settings, and raise the limit above 60. Recent Windows builds allow up to 480 FPS where the game and your monitor support it. Higher limits increase CPU and GPU load, so raise it gradually.
