If I have a suitable version :). Not to low not to high. Typically, you prefered a more advanced version. I didn't expect such an "old version" ;). As you know 8.1.0. or 8.0x are no longer supported. The error message of the system didn't tell me enough to solve the question by myself. Also, the advice: do a manual update was misleading.
Just sharing my thoughts....
But anyway.
Now the update was running as usual without any problems which was my goal.
