Fatal Error Message

[Anonymous]

Out of no where I started getting message: "Fatal Error unhandled e0434f4dh exception at fdab9e5dh" which then prevents AutoCAD LT 2010 to start.  I have uninstalled and reinstalled twice and both times added Update 2.  Any suggestions?

What changed on the computer all of a sudden?

Something triggered the change and now that you have doen the re-install route you may never find out.

Look to seee if there were any .NET updates to the system.

Did you run a Registry Cleaner perchance?

Any Norton products on your system?

Restore the computer to a week ago. If AutoCAD resets itself you are good to go.

If not:

REVO UNINSTALLER The free version on its most aggressive setting will get rid of all files.
Use this as the uninstall instead of Windows.

Then follow this advice from Autodesk:
