I have a few users that are trying to use the Solidworks Inspection Add-in in Solidworks.  The stand alone version functions fine and we have available licenses.  We are running SW2015 SP3 and Inspection 2015 SP3.  The inspection add-in inst even an option on the add in list and the icon is grey'd out.  Everything works as it should on my machine which is running the same SPs.  Has anyone experienced this?  Is it a Windows update issue? Should I try a fresh install? I am going to get my VAR involved but iIthought I would see if this is an issue that has been seen before.

Any Help is appreciated

Thanks

Brad
