Here is what I'm guessing tell me if I'm wrong, you had Style XP installed and you let the 30 days free trail expire. Right? and now the program won't install, because it gives you a .cpp errror, getting warmer?
1. Here is what I would do, if you like the program buy it, it's worth the 20 bucks.
2. If you don't want to buy the program get the hacked uxtheme.dll from tgtsoft own's site, it will let u continue to use the themes, but you'll have to load them different
If you don't want to use Style XP there are other chooses like Windowblinds, Geoshell, Litestep, etc.
