D11 Startup problem

[M.Joos 29]

Last week I sucessfully installed D11.  Since then I continued to work with D10.4.2 until today when I tried to start up D11 again. Now I received the follwoing error:

Confirming this error dialogs leads to many more with similar messages: D11 is trying to load D10.4.2 packages. Does anybody have any good idea why this happens?

Migration Tool copied registry entries from D 10.4.2 to D 11? There is a button "Version upgrade" in Migration Tool during restore, which must be clicked (or manually disable "some" items in the list).

Thanks for the hint - indeed, I fiddled with the migration tool - I think it's usability is very bad. I will look into it, and maybe jsut need to reinstall - haven't done much anyway.
