Value has been read from Registry so I have sufficient permission while I'm Administrator as well.
In Addition I tried now type = RegEntryType(topkey,keystring,32) and type = RegEntryType(topkey,keystring,64) which both still fail :-(
I uses that function regulary but I have no idea why i doesn't work this time ;-(
Additionaly I tried my local machone as well, with same result
Any help/hint is much appreciated
