I figured it out. Yay! The problem, of course, lies with Vista. It won't allow you to write data into the Program Files directory, but instead creates a Virtual Drive under Users/Your Name/AppData and makes it appear that the data is in the Program Files folder. So why is this important?
Because the first time I extracted my char.lgp, it was a modified version, and was saved in the Virtual Drive. When I uninstalled and deleted the directory in the Program Files, because the extracted char.lgp was actually in the Virtual Drive, it remained. So, I deleted that Virtual Drive, reinstalled, and it worked. Sometimes, I hate Vista.
So, here is my problem.
I can unpack char.lgp just fine, but when I run NPC RP v0.6, I get the following error:
This program cannot update the installed version of MyProduct because of the following reasons:
C:\Program Files\Square Soft, Inc\Final Fantasy VII\data\field\char\aacb.p: unknown version.
I don't have the Hand Model Mod installed. The only thing I have installed is the 1.02 patch off of a fresh, maximum install.
I am running Vista. Can anyone help?
