Ok, you could play with reported windows version - probably application checks for it to guess is new code here or not. Win2k doesn't support comctl32 v6, so it's worth a try.
Well, the homepage says it's "available for Windows XP and above", so I guess it probably doesn't do anything special for Win2k. I tried it anyway but it didn't seem to change anything.
