I had to replace my computer and it came with Vista 64 bit OS. I have installed all my AutoDesk products including Inventor. With some minor changes for Architecture 2008 I have them all up and running fine except the Content Center in Inventor. I get errors when I am installing with setup64.exe at the ADMS check list splash screen. I get a failure in the checking ASP status box, requiring an action which says: "ASPX file fiailed to run at URL:http//localhost/TestASP/TestASPNet.aspx". When I try the diagnostic suggestions it does not work. I also get two warnings: "Check IIS contection time out" and that I change to 900; and "Checking for know firewall" which I have Norton and I turn it off. The result is the same. The program loads and works but the Content Center does not. Any suggestions? I have solved the problem when it occurs with XP but cannot seem to get a handle on it with Vista. Since I am an instructor and I need this software I am in need of a solution ASAP. I have done a clean uninstall and reinstalled and the Data Manager didn't load and thus the content center did not load.
