Why does Vista Transformation Pack 7 gives problem while installing?

Answer 1

I would advise you to not install the vista transformation packs. They are full of bugs and have many errors. I've had a couple of them on my computer and it slows them down drastically, and half of the time, it does not display things correctly anyway. And another big thing is that they never completely uninstall. I uninstalled 5 and 6 and they never fully restore the XP look. Maybe 7's different, but I doubt it. The reason why it is not installing properly is probably because there are bugs and errors in the program somewhere or you are doing something wrong.
That's only my opinion. The most important thing is that you have fun with it.
