Orphaned LP existence for Inventor

Problem

When you uninstall an Autodesk Inventor Beta release, the language pack may not fully be removed from your system. This prevents any future successful installations of Autodesk Inventor.

To resolve the problem:

1. Uninstall the orphaned language packs using Windows Control Panel.
2. Reinstall Inventor.
3. If you are prompted to remove language packs but there are no language pack entries in the Control Panel, open a CMD window and uninstall any remaining language pack using the command line:

a. Identify the corresponding 3-digit product code for the orphaned language pack from the below product code table.

b. Open the CMD window and input the command to uninstall the orphaned language pack manually.
