I am trying to install ZenOn WebClient 6.51 SP0 on a Windows XP SP2 PC logged in as administrator user.
Unfortunately the Installation hangs up at about 85% while trying to "copy new data"

Getting following error messages:

"Fehler beim schreiben in Datei: IPH_WatchDog.dll
Überprüfen Sie, ob Sie auf den Ordner zugreifen können."
-> Error with writing in file: IPH_WatchDog.dll. Check if you have permission to access the directory.

"FDI server error."

Any ideas?
