Mezzmo won't run. Mezzmo.exe is in its correct folder location, but double-clicking on it (or right-clicking and selecting "Open") produces nothing: no error message, no temporary indication that the program is running in Task Manager, no errors popping up in the Windows Event Viewer, nothing. It's like Mezzmo.exe is just executing a single "return" instruction and doing nothing.

I haven't changed anything with respect to Mezzmo recently, haven't tried to manually update, haven't touched the settings, haven't added new media files, nothing. It just stopped working.

I'm wondering if a Windows Update could have done this? Or a failed Mezzmo update in the background?

Mezzmo is installed on a Windows 10 64-bit system with fast quad-core processor, 16GB RAM, and plenty of space on the C: drive. Everything else on this PC works fine.

Any ideas what's wrong?

What should I do? I'd like not to lose my settings.

Thanks!
