Hey guys, I'm having trouble with Revit, a friend has given me their computer to take a look at (HP Pavilion dv6) because they can't get Revit working. When I go to launch it, the process starts and appears in Task Manager but then ends after 30 seconds or so. When I go to uninstall it from Control Panel, it says that it's already been uninstalled. When I look for uninstallers, I find UninstallTool.exe and run it but it hangs and won't close unless you end the process or shut down/restart the computer. Any ideas? Ninja!
