Error help?? Thread

Hey there, i've been searching for a Sephiroth mod for about 3 days now for FFVII for the PC
I searched the damn internet for this long and wth I can't find anything, what is this the twlight zone.
I found a mod on here, which appears to be only viable one, as everywhere else this doesnt exist or is now broken or missing
which is strange as one would think there would be a hell of well known mod for perhaps the most popular FF character ever.
This is the link to the mod I found Moddb.com

Everything seems to work out, but when i try to run a certain program of the mod to finish the install I get an error as follows

"The version of this file is not compatible with the version of windows you're running. Check your computers system information to see whether you need an x86 (32-bit) or x64 (64 bit) version of the program, and then contact the software publisher"

Any help or info would be awesome.

Simple it appears to be.

The installer is for a 64x version of the OS and you're running on a 86x that is a 32 bit Windows system.
