Just an update:
I’ve followed all suggestions and also the new article from Dmitry gave a lot more insight (If you have problems running Excel Command on Server).
But unfortunately I was not able to solve the issue (same issue remains). I’m giving up since the functionality to use Excel macros is not really a must have and to invest more time in the issue is not worth it for us.
The issue seems to be related to the VM, Windows account and/or Excel. I don’t think it’s a EasyMorph issue.
