Haaha, For solutions I am like a badger on a hunt.
Yeah, and I looked for entries in the registry before and did not find any with relevance to this phenomenon.
I did a S&R in the registry and changed all locations from SL4 to SL6. But that did not help and SF11 still called SLP4. So I found the other solution with a junction.
Actually with SLP 4 installed there was no such entry in HKEY_LOCAL_MACHINE\SOFTWARE\MAGIX
However, thanks for your reply. Maybe I’ll try this later. Just for curiousity…
