Requiem wont install says dont have black plague

[toucan_hammer]

Wow, i cant even get that lucky! When i double-click the installer a dialog box pops up saying "Penumbra Requiem requires Black Plague to play" With an OK button.

I completed Black Plague and have it installed in the default directory.

I even tried placing the installer in the root directory of black plague and throughout the Black Plague Directory and still nothing.

I checked my registries for accurate entries and ran a registry cleaner (since Black Plague used to be installed in a different directory).

Nothing seems to work! Is there a way to rip the contents out of the installer, i'll install the damn thing manually.

I'll keep trying stuff and looking for answers and report back what ever i find.

System:
Windows XP Pro SP2
Intel Core 2 Quad 2.7 GHz

(Yeah i know, its overkill for a game like this. But i love this game!)
