...

now finally i got a workaround.

I set up a new windows 10 pro on a pc from scratch without any other applications installed. I did an offline installation to suppress any updates coming from elsewhere. i finally made an image backup from the disk beeing able to test any situation.

so what i found out was:

1. after getting all windows updates and installing the digital paper app, i can't update the pad(error message as shown above)
2. restoring the previously made image without any updates and installing the digital paper app let me install the pad's image without any errors.

Now i try to find out what the difference is between the two installations.
Perhaps it can be done parallel via virtual machines.

thanks for any help from your site.
