In case it passed you by, Inventor update 2 for Autodesk inventor 2013 and Inventor Professional 2013 was released last week.

As well as addressing a number of stability issues and other issues including those raised automatically by customer error reporting, the update also includes a hot fix for the Inventor vault add-in.

The update can be downloaded from the Autodesk website here and as usual please ensure you read the readme files in full before installation.
