At first I removed Securemote by the the Add/Remove program option. After two days I wanted to install it again but I got the FireWall-1 Error message and was not able anymore to install Securemote again. After I checked the registry and deleted a key that has a relation with Firewall-1.
Up to now I'm still unable to install Securemote again.
Reinstalling XP from scratch is the far and far last option I will use because of the applications I need to use at this moment.
This is a weird error.
I scanned through the registry with many different search strings that might have a relation with Securemote or Checkpoint or Firewall-1 or firewall etc. .
Kind regards.
