Removing Trialversion on Win 10

[UR_]

I think, there is as issue with my installation, using win 10 64bit (Home and same on Pro)
Behaviour can reproduced by these steps:
- Install Qcad using "qcad-3.16.3-trial-win64-installer.msi" or "qcad-3.16.4-trial-win64-installer.msi"
- start qcad.exe elevated to admin rights
- remove Pro-Extension

- restart qcad.exe, and everything is fine
- exit qcad
- double-clicking a dxf-file on desktop causing this popup

- after finish, we are in trialmode again

BTW opening same dxf-file with open dialog from qcad works.

looks like Win 10 is aware of renaming some *.dll to *.disabled
Win 7 64 bit Pro works as expected
Thank you for your attention!

It works, but i dont know why
In registry these entries can be found:
