    Also which version are you trying to start and for which version do you have a license key?

    Richard Huggins - They refer to restarting the PC.  99% of the time, that means its Windows.

    Last time I had problems, support got me to set up a new user account and run capture one from there. Helps isolate where the problem is.

    I have the same problem with C1 16.3.8 and a Windows 11 PC. C1 has become increasingly sluggish, graphics card fans were running at full speed. This often happened with older versions, but has rarely been the case since version 16.3.2. I closed C1 before it came to a complete stop to avoid damaging the database. After that, a restart was no longer possible.
    I tried to open another catalog and a session by double-clicking in Explorer, also without success. Reinstalling the C++ redistributables and C1 was also unsuccessful. I then reinstalled version 16.3.2 and everything is running smoothly.

    As an addition: No window opens when restarting. C1 only appears for approx. one second in the key manager before it is closed without an error message.

    Make sure you are running a compatible version of Windows and make sure your graphics drivers are current. I have also read of bad experiences with game drivers vs studio drivers for graphics cards. Game drivers tend to be more bleeding edge and could have bugs. Studio / Creative drivers tend to be more stable and well tested.

    Could some anti-malware / anti-virus software be getting in the way? Can you check their logs?

    Have you looked at the C1 Log Files?

    Do the Windows reporting tools give any indications of errors ?

    I'm using the latest studio drivers. Windows 11 should also be a compatible version.

    Has anything changed with V16.3.8 that a virus scanner could be sensitive to? As described above, C1 could be started once (but only once).

    Where can I find the C1 log files?

    I have not yet dealt with the Windows reporting tools. So far, everything has always run smoothly. I wouldn't know what to look for there either.

    I believe there was something higher in this thread or in another thread where someone found that a service or library was being blocked by an A/V or malware tool. I cannot remember what it was. Once they marked that it was safe their problem went away.
