Capture One won't start, or crashes often

I've written about this before but the threads seems to have died, so I'm starting over.

I haven't been able to use Capture One effectively for about 3 months. By "effectively", I mean that if I manage to get it running, it only works for an hour or so before crashing. That is a best case scenario. More often, it won't start at all.

Phase One technical support got in touch with me about this, which I appreciate, but was unable to solve the problem. They looked at my dump files, which implicated the license manager. I use the Phase One license, because I have two Phase One cameras. This means I use the same license code for all versions that came with my cameras.

The closest we came to a solution is for me to delete some CaptureOne folders that are relevant to the license, then reinstall the software and re-enter the license. That usually (not always) works, but only for one session. If the session goes too long, over an hour or so, it will crash. If it doesn't crash during the session, it crashes on exit.

I consider Capture One to be an essential tool. Currently, however, it is no more effective at editing or managing photos than a butterfly net. The only solution I can think of that might have a chance of working is to reinstall Windows. That would entail reinstalling about 40 other apps, their passwords, and other things on various websites. Alternatively, I could buy a new computer and run Capture One on that. I don't like either option, for what I hope are obvious reasons.

I hope the people at Capture One can figure this out because for now, I've had to remove Capture One from my workflow. I had eight years of worry-free use of the software. I like C1 quite a lot, but if it won't open, it doesn't exist.

  Update: I just tried uninstalling, deleting the relevant folders, restarting, and then installing an older version of C1 (v. 20). It won't start either. Every other program works perfectly on my computer. C1 is the only one that consistently fails to start.

  Hey Andrew Paquette, if you haven’t already, I recommend requesting support from the Capture One team by clicking the Request Support button at the header of the page.

  Regarding the issues you described, creating a new OS admin user is similar to having a new clean OS. For testing purposes, you can try running a supported version of Capture One Pro under this new user. And make sure nothing else is running in the background.
