Issue:

Launching Inventor results in a ‘System Error’ with similar missing dll (MC3.dll, tbb.dll) files in the error message:

Causes:

• The Inventor shortcut to run the program is set to an incorrect Inventor.exe path.
• There is a problem with the Inventor installation and the program needs to be reinstalled.

Solution:

First verify that the Inventor shortcut used to launch the program is pointing to the correct Inventor.exe file location.

Right-click on the Inventor shortcut and select Properties.

• Inspect the Shortcut tab and the Target path to Inventor.exe:

• In Windows Explorer browse to the same path to verify that the Inventor.exe file is located there.
• If incorrect, change the path to the correct Inventor.exe.
• For example if Inventor is installed on the C drive the path will be in C:\Program Files\Autodesk\Inventor version\Bin\Inventor.exe

If the path is correct but Inventor will not launch uninstall and reinstall the program.

• Uninstall Inventor from Control Panel.
• Get a full download of Inventor:

From your Autodesk Account under Products & Services choose Download:

From the Autodesk AVA 

• Reinstall Inventor from the downloaded files.
