Vault Office Addin Not Appearing After Installing DL19837065

After installing DL19837065 (link no longer available as it has been unpublished), you may notice that the Vault 2013 addin for Microsoft Office applications either stops working (the icons are greyed out) or you may get an error similar to this when trying to run them.

Could not load file or assembly
'Autodesk.DataManagement.Client.Framework.Vault.Forms, version=17.0.0.0, Culture=neutral, PublicKeyToken=aa20f34aedd220e1' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Autodesk have re-released a fix for this issue that includes additional fixes in DL20133057.

So uninstall DL19837065 and install the newer Hotfix.
