Orphaned LP existence for Vault
When you uninstall an Autodesk Vault Beta release, the language pack may not fully be removed from your system. This prevents any future successful installations of Autodesk Vault.
To resolve the problem:
Uninstall the orphaned language packs using Windows Control Panel.
Reinstall Vault.
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:
Identify the corresponding 3-digit language product code for the orphaned language pack from the below product code table.
