Problem solved! Though not by installing the latest runtime version of VB6... While waiting for your reply I was just trying some things. One of them: Plain deleting. I made a backup of and deleted my directories "\Config.Msi" and "\Documents and Settings\M ~1~HOP", did a reboot and retried the update procedure. That was it! Should have tried that before, wasted two days on the net looking for an answer. I will get the lateste runtime version of VB6. Just to be sure Thanks for helping me out!
