B-17 Flying Fortress 2 Patch 1.05

[sharp_n_fuzzy]

I just downloaded the 1.05 patch for b-17 and when I go to install it, it says that the game isn't installed on my machine. I tried reinstalling the game many times from my backup cd (can't find my original), I think my registry is messed up.... what is it searching for in there? I looked through it and I have an entry for b-17 under local machine/ software/..... i don't know maybe its missing something. Anybody know what the registry entry should look like?.... or any body know of a good program with which I could get the data out of the patch... i got the cab files out but i've tried endless cab file readers but none can extract them.... help!
