Upgraded server crashes at start up

Upgraded my dedicated server to the latest version and it crashes on start up. What are the new server requirements and dependencies it needs to run please?

Hmm... this is an internal Unity error. You could try to verify the files, as suggested by noci and james1bow , just to make sure no files are corrupted...

However, I'm afraid that this error is because of Windows Server 2012... we've updated to Unity 6, and they dropped support for older Windows versions unfortunately (Windows 7 and Windows 8). Since Windows Server 2012 is based on Windows 8, chances are high that it's just no longer supported by Unity Sorry for not having any positive news...

Thanks Red I appreciate the help, that saves me allot of time messing around with redistributors , I will install server 2016 which i think is based on windows 10 and retry

I have finally got this working. Because of Unity 6 the minimum server requirement is MS Server.....

Windows 10 version 21H1 (build 19043) or newer, running on workstation and rack form factors, without emulation or compatibility layer

so this is also the NEW minimum server version requirement to run RW server after the season update. I managed to get a copy of windows server 2019 which runs nicely on an old Dell optiplex 390. This version runs RW server without having to install any service pack updates.
