AVG Anti-virus incompatibility under Windows 7 64-bit

Recommended Posts

At the August 2010 RockWorks training class, two attendees with new computers ran into a recurring bug report with the following error:


The requested operation cannot be performed on a file with a user-mapped section open.

We determined that this error was caused by the AVG anti-virus program running under Windows 7 64-bit. We replaced the anti-virus with another program and the error no longer appears.
