Vault Add-In won't load in Inventor-'System.IO.FileNotFoundException...'Autodesk.Inventor.Interop...'

Issue:

The Vault Add-In won't load in Inventor with an error similar to the following:

'System.IO.FileNotFoundException: Could not load file or assembly 'Autodesk.Inventor.Interop, Version=...'

Performing a repair on the 'Autodesk Inventor_version Add-In' in Control Panel doesn't get rid of the error.

Inventor-Interop-Add-In

Manually trying to load the Inventor Vault and Edm Add-ins keeps them unloaded.

Causes:

The error is caused by a missing folder and .dll file, see this Autodesk article:

"System.IO.FileNotFoundException: Could not load file of assembly 'Autodesk.Inventor.Interop, Version=##.#.#.#..." in Inventor when attempting to use or install the Vault Add-in

For example this based on the error above the following folder is missing:

Inventor-Interop-Add-In-NETfolder

Solution:

1.Uninstall and reinstall Vault Client to get the folder back.

2.Install the appropriate Vault Client updates based on the updates installed on Vault Server:
