Installer problem

Whenever I start the installer it freezes at the "checking integrity MD5" stage. I also noticed that when I end the program through the task manger window there are two instances of the setup. I have also downloaded the new version from almost every mirror.

Your help is appreciated

It takes quite a while to do that check. But if you are unable to install, you can use 7-zip to extract the files into your RTW directory. You'll have to make the shortcut manually then, however.
