Autodesk Navisworks Service Pack Available

On September 14th, 2010, Autodesk released Service Pack 1 for their Autodesk Navisworks 2011 products.  The service pack applies to Navisworks Freedom 2011, Navisworks Manage 2011, and Navisworks Simulate 2011.  When running the service pack, any and all of the 3 Navisworks packages installed on the computer will be updated.

This service pack only updates individual installationsof Autodesk Navisworks 2011 products and should not be applied to Navisworks products installed as part of Autodesk Factory Design Suite 2011.  If you have Navisworks exporters installed on any packages other than Navisworks, be prepared to uninstall those exporters if you have an error message when installing the service pack.

The 32-bit version is a 208 Mb executable download and the 64-bit version is a 275 Mb executable file, so be prepared for a lengthy download if you do not have a fast internet connection. 

Like many updates, installation of the service pack will place new program shortcuts on your desktop.

According to the the Readme file, the service pack fixes the following defects:
