Download AddInLoadRules.xml and manually edit the file in a text editor. To manually edit:
Open the manifest file for the 3rd party add-in that you want to add to the Inventor Add-In Manager.
Note: The manifest file for an add-in is an XML file containing a description of the add-in. The file has a .addin suffix. The Add-In Manager reads this file to know what add-ins to display and load. On Windows7, the .addin files are installed to ProgramData\Autodesk\Inventor 2016\Addins.
In the AddInLoadRules.xml file, copy or replace the GUID you are changing, (the string between { and } ), with the ClientId GUID from the manifest (.addin) file for the add-in.

Edit the comment field (between <!—and --> to reflect the name of the add-in.
