I have Sins installed and can start the game. But when I try to install the patch I get the following message:

[Sins of a solar empire not found] [X]

The path registry value at
HKEY_LOCAL_MACHINE\SOFTWARE\Stardock\Drengin.net\sins
appears to be blank.

Please make sure you have the game installed.

This update installation will now exit.

Has anyone encountered the same problem and by chance found a sollution?
