When you installed, did you right-click on setup.exe and choose "more->run as administrator" ?
under C:\Program Files\ANSYS Inc\ANSYS Student There should be an install.log file and maybe a an install.err file. Do those shpow any errors?
If you did not right-click run as administrator, try uninstalling and reinstalling.
Also, check visrus scanning and firewalls for any blocking going on.
