Fixpack error in BGT installation

I get the following:

Installing fixpack...
Copying and patching 43 files ...

ERROR locating resource for 'COPY'
Resource [aasim.cre] not found in KEY file:
 [./chitin.key]
Stopping installation because of error.

I installed Baldur's Gate, ToTSC and the patch allready a few time.

They are outside program files also.
