Help with UniWS

[JDielentheis]

So I made an account on this site for the sole purpose of getting this question answered so I hope you guys can help me :)
I recently bought KoTOR off of Steam and am looking to get it running in widescreen. I downloaded UniWS but when I try to use it, doesn't seem to realize my Program Files (x86) folder is there, which is the folder that my KoTOR is in. It only detects the regular Program Files folder which has nothing of real importance in it. How can I fix this so I can change my KoTOR resolution?
