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"
It is possible to set the shortcut to run as Admin by default, to do this, right click on the icon, choose "Properties", on the "Shortcut" tab, under "Advanced", select "Run as Administrator", then "Apply"
Note that in both of the examples above, you may need your IT administrator to provide you with a password.
