I both installed it and then tried without installation (zip file).

It doesn't start.

I tried both v1.2.8 and v1.2.9 beta and they both worked for me when starting them from a .zip file.

1. What version of mrv2 are you trying and where are you downloading it from?
2. Can you fire it from the command-line (cmd.exe, Windows terminal, etc) and see if you get any errors?

Downloaded from here, github, both v1.2.8 and v1.2.9 beta
vie commandline it tells me:
ERROR: RtApiWasapi::getDeviceInfo: Unable to retrieve device mix format.

I am sorry to say, Chris, that this is one of the long standing bugs in mrv2. It seems this is the same issue as that of #194. So far you are the second person that reports it. It seems to happen with some audio cards. Unfortunately, I don't have a way to test it or debug it.

As a final test, please do this:

1. Update your audio drivers and see if that addresses it.
2. Make sure you don't have any applications that use audio running.
3. Start mrv2 again from the command-line and use the -log option to see what it prints out. Report it back here.
4. Upload an image or description of your audio setup here to see if there's a correlation between your setup and that of ERROR: [] Cannot initialize audio system #194.

It happened because usually I do not install the audio driver of my nvidia graphics card. Just the display driver.
My mainboard has it's own sound and I didn't want to have those additional audio interfaces showing up.
Apparently this caused the error. I just installed the newest version of nvidia studio driver with the audio driver and it starts without an issue.
Thanks for pointing me to the issue! :)
