Munted Install

Hello, I recently bought Sins, and when i put in the disk, it asks for my permission to run Sins of a solar empire setup. then a box come sup hat looks like the usual preparing install aware whatever box but has ([] is a square) [][]Stardock Corporation10[][]Stardock corporaion..... and so on as the header and contains nothing but a bar. Then Sins of a solar Empire -InstallAware wizard opens and after pressing nexti goes to the liscence agreement, then after accepting that it goe to the easy install/advanced install screen. After that it goes to the installing screen, with the Status: thing staying blank untill a blank error box appears. When i lick Ok it goes to the finished screen, which has the message: The installation for Sins of a Solar Empire has failed. "Fatal error during installation" Please check your setings and try again. My system passes the minimum specs, and the demo ran fine. I fully uninstalled the demo, inluding desktop shortcuts and the startbar. thanks in advance.
