The log output shows a lot of VCRUNTIME140_1 errors. Have you checked your system has the newer runtime identified in the Important section of release on Github?

See https://github.com/CasparCG/server/releases/tag/v2.5.0-stable

Hello,

Thank you for taking the time to look at my problem.

No, I didn’t install the update; I simply didn’t see the warning.
Perhaps the installer should check for this prerequisite and notify the user.

Thanks again, and Happy New Year!
