SFIV Moveswap help

I’ve been trying to swap the movesets in the PC version of SFIV, and I’ve run into some problems. I’ve downloaded the Automated Move List Switcher found here: AutoIt Scripts

and have run into some problems…

when I run it, I get the error: “Error: Dependency program offzip.exe failed to extract the move set file. Perhaps it is corrupt.”

I’m not really sure what to do, and any help would be appreciated.
