Why MuMuPlayer Crashes with Traditional Frame-Grabbers
MuMuPlayer’s virtualized graphics stack relies on a headless MuMuVMMHeadless.exe process that multiplexes both D3D11 and Vulkan calls. Many generic frame-capture tools inject DLLs before this process finishes initializing its swap-chain, triggering access-violation crashes. RenderDoc Pro patches the injection timing and wraps late-bound swap-chain creation, so the virtual GPU is ready before any calls are intercepted. The result is a stable, one-click capture workflow.
RenderDoc Pro Quick-Start for MuMuPlayer
- Launch RenderDoc Pro and open the Launch Application dialog.
2. In the Executable Path field, enter
“C:\Program Files\MuMuVMMVbox\Hypervisor\MuMuVMMHeadless.exe”

3. Click Start.
4. Run MuMuPlayer manually from its desktop shortcut or launcher.
5. RenderDoc Pro will attach to the MumuPlayer automatically now. You will see D3D11 by default; switch to Vulkan if you’d like to anaylize the vulkan pipeline.
