PR Installer wont open.

[FuriousGamer13]

I used to play Project Reality a long time ago and recently wanted to try it out again however every time I try to use the easy launcher and when it's done downloading I try to click the start installer button but it never works and I don't know what to do.

if the button doesn't work go to your downloads folder and mount the installer manually or if that already worked go to the mounted DVD and launch the setup.exe manually.
