Capture One not starting



  • Gert Kaasschieter

    I’ve re-installed CO 16.4.1 on my old laptop (also Windows 10 (pro), but not updated with the latest cumulative Windows update, and CO started normally. My guess is that the Windows update might be the cause. The log file gives me the following information:

    Faulting application name: CaptureOne.exe version:

    Faulting module name: Coreclr.dll version

    The coreclr.dll is part of I really hope CO technical support will address the issue with the highest priority. At this moment I would not recommend W10 users to install the latest cumulative update KB5039211.

    FWIW, I'm running Windows 10 Home with KB5039211 installed and I have no problems with CaptureOne starting.  However, I upgraded to 16.4.1 after the patch was installed.

    Yesterday I encountered the same issue and lost a lot of time to figure it out. It seems that the reason was KB5040427 update which updated .NET framework (KB5041081). I managed to revert it by installing previous version of .NET (8.0.6 - - runtime installer) and CO started to work again. Thanks for emotional roller coaster, Capture One.
