Inventor.exe -System Error

September 5, 2022 Joanna Gryszka

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 go to Quick Links at the top right and choose Download Autodesk Products:

  • Reinstall Inventor from the downloaded files.
