I have a machine that I just setup with Windows 7 Enterprise and everything is working fine on it except one thing. We have an application called Matrix that I am trying to install and it is not working. I browse to this installation folder and double click on setup.exe as I have many times and the setup program appears to fire off, but the setup window never displays on screen. When I open task manager I see that setup.exe is running, but again there is nothing on screen for me to make the installation run. What could be wrong? This makes absolutely no sense. I can go to another machine and this setup runs just fine. Also I am able to install any other application on this machine. Please help!
