Now for a coffee break, and thanks a lot!
The only change to the system since August was installing Python 2.7!
Some few crashes still occur, so I had another check of the path variables and at the User variables I found another PATH = %APPDATA%\Python\Scripts.
I deleted this PATH, and after restarting Windows, Calibre didn't crash again!
