Disk4mat, thanks for your reply! That's the point: I do not want to exclude the whole key (HKLM\Software\Microsoft\Windows\CurrentVersion\Installer\Folders) but the single "program entries" only. If supported at all it should be sth like
HKLM\Software\Microsoft\Windows\CurrentVersion\Installer\Folder@C:\Dokumente und Einstellungen\Anwender.SERVER\Desktop\CamSpy
I suppose that's not possible, is it!?
TIA, mcman
