"WindowBlinds has detected a problem with core files. Please contact support with error message -7"

I'm considering upgrading to WindowBlinds 11, just for the new Windows Classic skin (currently using True Classic, but maybe the "official" skin will be better).

But before I install that or any other software on my real machine, I want to test it in a VM.  So I'm trying to install WB 11 on Win10x64 in VMware Workstation, fully updated to 22H2.  But multiple times during installation, and when trying to launch WB, it fails with the following error:

WB11Config

WindowBlinds has detected a problem with core files.

Please contact support with error message -7

OK

The only other forum post I found on this was https://forums.stardock.com/515465/page/1/, and the only suggestion there is to make sure Windows is updated.  Which I've done.

Any suggestions?  Thanks.

This will be an issue with slow updates to the OS root certs.

Brand new installs are more likely to show this which your VM is.

If you right click on wb11config.exe and pick properties and then digital signatures you should see an error.  If you wait 10 mins and then reboot it may help.

Thanks!  Rebooting fixed the error, although before rebooting (and while still getting the error), I didn't see any error in the Digital Signatures.

Why is this problem not solved ?

 

I have been reading several topics with solutions to the problem, unfortunately  they

are in English and very difficult to follow. I do not understand how to install a trusted

certificate and have a not working Windowblind 11.....

Is it possible for Stardock to offer a certificate for download and install somehow?
