When trying to update to the new version that was released on 3/4 I get an error message that I never received before. Current version is 15.6.2.1015 and the new update is 15.6.3.1018.

I tried to start the installation on my local pc and that worked fine so no issue with the installation file either.

I have tried to restart the server without success.(Also tried run as administrator) Any idea?
