You may come across instances where Inventor will not load an add-in or a DLL, this is sometimes manifested in an error message, or a function just not working.
When installing Inventor, it should always be done with the UAC turned right down, with the user logged on as an Administrator, and with the anti-virus disabled.
While logged on as Administrator, it is advised that Inventor is fired up, as this registers all of the relevant DLL’s with the Windows operating system.
As a user, If you are still having issues, a nice workaround, is to run Inventor as Administrator, this can be achieved by right clicking on your Inventor icon and choosing “Run as Administrator”
