Fatal Error on handled access violation reading 0x0000 exception at 77e6cd71h


please help - thanks.

Answer
Zion:
This error is caused by a virus.
See this article in the Autodesk knowledge base:

otherwise, look here:
When you start AutoCAD, you receive one of the following error messages:

Unhandled access violation reading 0x0000 exception at 77e72b5ah
Unhandled access violation reading 0x0000 exception at 77e868c5h
Unhandled access violation reading 0x0000 exception at 7c4ebf97h

Solution


These errors are caused by the w32.pinfi virus.  To check a computer for the virus, look in the registry for the following key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer.
If the PINF value has been added to this registry key, the virus is present.
To restore normal AutoCAD operation:

Disconnect the computer from the network.
Use the Add/Remove Programs function in Windows to uninstall AutoCAD.
Remove the virus with anti-virus software using the procedure recommended by the software manufacturer.
Check other computers on the network for the virus and, if present, remove the virus from them.
Reinstall AutoCAD.
Reconnect your computer to the network.

Good luck removing the virus.
