Thank you for reply!
I do use a VPN (Surfshark) but issue persists even when logged off. In the end I uninstalled Surfshark, disabled my Antivirus, and un+reinstalled Start11. But to no avail...
The error message shows up after every restart. I've used Start 10+11 for several years on multiple PC's, but this issue only showed itself with this update..
I'm not very familiar with Win-policies, but all of them looked unconfigured. Anyways, I tried to delete policies with CMD RD /S /Q "%WinDir%\System32\GroupPolicy" and RD /S /Q "%WinDir%\System32\GroupPolicyUsers" with a subsequent restart. Unfortunately this didn't resolve the issue either..
It's not related to corrupt download. As this issue affects both my PC's and each was updated separately.
Open for suggestions since I'm running out of ideas.. Hope Stardock can look into any changes in ver 1.1 that could cause this issue.
