ManyCam Studio (Windows 10) crashes frequently

The ManyCam Studio edition is a fantastic app – when it doesn’t crash. Why does it crash so easily and often? I’m running it on a desktop computer with ample processing power, and I’m using it to enhance Zoom-based worship services, primary by switching between 6 to 8 presets in which I have placed a couple of short videos, various still photos, bottom-third titles and other standard content. Windows Task Manager does NOT indicate that the CPU, RAM or GPU are being pushed too hard, yet ManyCam frequently crashes nonetheless. When it crashes, I open again from a shortcut and it returns to the screen in about 30-60 seconds, with the same presets in place. But during that crash time the ManyCam feed into Zoom is dead. Please, please help! Thanks!

Please upload crash dump files (all *.dmp) from C:\ProgramData\ManyCam\CrashDumps somewhere (Google Drive, Dropbox) and send the link to This will help greatly.
Thanks in advance.

Done. I look forward to hearing from you. Ben

leo, have you made any progress after inspecting my dump files? Please advise. Thanks. Ben

Hi, Jumping in here because I’m also now having trouble using ManyCam on Windows 10. Everything was working great for me in early December. But after returning from winter break, the application is stalling for me during meetings. Mouse cursor hangs every few minutes, and after about 10-15 minutes of broadcasting video, the video stream drops to under 1 frame per second, and doesn’t recover unless the application is closed and relaunched.

No actual crash is occurring for me, and the application hasn’t produced any dumps. I tried disabling mouse capturing etc, but that didn’t help.

Update: Nevermind, after experimenting further I found that my usb3 card was over-saturated, and switching my camera device over to another channel resolved my issue.
