Currently looking at the infocentre as being the possible casue of the issue?

Have defintiely turned off the hardware acceleration - Last retart took 8 minutes and 12 seconds. Sun, at 1:03:51 PM | Revit Architecture 2011 is not responding in Windows 7. I Hope and I Wish to LEARN more, and more, and more. Did you turn ON the " Hardware Acceleration"? " The time to start a Revit session from scratch is currently 4 minutes? " - I don't have Windows 7 but with that machine it's not normal take so long to enter in Revit. Sun, at 12:30:20 PM | Revit Architecture 2011 is not responding in Windows 7. Has completely stopped some of my current projects. All the other software loaded on the system is working fine. Any ideas apart from completely rebuilding my system from scratch. Seems to hang on the "recent files screen" and I do remember there was an issue with this screen and its compatibly with IE 8? with Revit 2010 64bit. So far, I have removed the entire 20 Revit suites along with the 2011 Max Design and reinstalled only Revit 2011, removed the virus software, cleanly uninstalled Revit 2011 following Autodesk's sequences, reinstalled the video drivers and still no joy.

The AutoCAD 2010 also slowed taking nearly two minutes to start-up. Revit 2010 had been running well for the last year. The existing Revit 2010 version also completely stopped and would not start.

The initial install worked fine last week but on Friday, the start-up times across the system starting slowing.

I don't think that hardware capability is the issue. The time to start a Revit session from scratch is currently 4 minutes? on a system that has been starting Revit 2010 in under 15 seconds. HI I am having the same issue - I was running Revit 2010 and trying to run 2011 (64bit) on a Dell M6400 notebook quad core system with Windows 7 64 Ultimate, 8G RAM.
