You need the runtimes for the original wm. I think all you really need is like .net 3.5 or maybe .net 2.0. Plus you have to make sure that your antivirus isn't freaking out about WME. Also make sure your using crazys mod version, as it's the only supported version on the forum. Oh and the runtimes for the original WM are in the orignial wm thread. (if you can't find them here and need to google them make sure you only get them from microsoft. otherwise you'll get adware and virusssssss'.)
