Notes and Warnings

Here are a few things I pulled out of the Installation notes:

Vault Users need to check the MUST READ section for important issues.

  • Update your OS before installing Autodesk Inventor 2011 Service Pack 1, especially KB952696 for Vista. Reboot your system after the updates are installed.
  • If you are running Windows Vista 64-bit or Windows 7 64-bit, please verify that you have the Microsoft fix for user mode callback exceptions KB976038. This fix ensures that Autodesk receives the correct data from Inventor 2011 error reports. For more information, and access to this and related Microsoft downloads, refer to Autodesk Technical Solution 15492718.
  • If you install Inventor 2011 on Windows Vista or Windows 7, when you launch it for the first time after installing Autodesk Inventor 2011 Service Pack 1, right-click on the Inventor shortcut, and use “Run as administrator” if User Account Control (UAC) is enabled, or your current user is not an Administrator group.

To verify the installation was successful, start Autodesk Inventor:

On the InfoCenter Help pulldown menu, select About Inventor. If the About box display reads: Build: 282, Release: 2011 SP1, the installation was successful.


There are a lot of things that have been updated. Check the installation notes link above for the entire list. My pet areas, Simulation and Analysis Environments got some help, but then so did every area of Inventor.

I would like to mention one in particular, and thank the Manufacturing Solutions Division for one of my bug submissions:

Changing model units to mm in Fusion causes models to scale up in Inventor.
