Domino Incremental Installer Issue

I am attempting to install fix pack 1 to my Domino server.

I get this error, which I am unsure how to fix.
I have tried to add the Domino key under the Lotus key in the registry. This did not solve the issue.

I have also added a new String value called Path to see if I just put a path there if it would realize Domino is installed.

This did not work either. The server runs fine, I can start it from the services panel, there is just apparently a registry issues with the computer.
