I'm also on x64 win7 Ultimate. I'll see what I can do as well about getting it to install. I've never made winrar ignore broken files, so can you tell me how to force that?
If you right click the rar file and select "extract files..." there is a check box in the bottom left that says "Keep broken files" check than and extract.
If you dont have winrar integrated into windows. Double-click the rar, then click the "Extract to..." button, which will bring up the same dialog as the above steps.
You will still get the errors, but it won't delete the file.
EDIT: I got the music working, not sure if this is related to x64, but what FF7 music was outputting lead me to believe it was working, upon further inspection (opening the FF7 music config), it has the correct plugins selected, but FF7 Music isn't using them. If you reselect the plugin it will load it into FF7 music and then it will work. So, as of right now, I currently have a fully working FF7 install on Windows 7 x64 and the Remix mod installed
(Minus the two corrupt files
). Once I find my original CDs I will do a clean from scratch install with them and let you know how it goes- but I'm fairly confident it will work.
The way I start the program (this matter because if you don't run FF7 as admin it seems to like to crash, at least that's my experience, is to start FF7 music as administrator, and then start FF7 via that. This method, so far, has been working perfectly.
