Looks like junk. It's my failure too (for not explaining), but you're not supposed to drop whole dlls from Vista or XP into images. Nobody will like 40+ MB of that trash.
Oops, I'm sorry, the install script does not install all files. I've fixed the problem.
For you who already downloaded the pack: open install.bat and remove the "/D" option in the xcopy command. Save and run install.bat again.
About the size: you're right, I could have made the files smaller, I just didn't have the time to do it, but I will.
