I guess your question doesn't make any sense, what is your definition of "not working".
Can't load them, missing, not functioning properly, can't find it, can't see it, wrong add-ins, etc.
Just went thru the same thing...
Fresh install and no add ins...!!
VAR just came across the fix last night (july 16).
Windows update is causing issues with SW addins.
Action taken and it worked.
***Search and remove windows update KB3072630***
Everything came back into existence.
PS: Thanks Garrett from Cadimensions...!!
That was a windows update issue, my var fixed it....
Thanks guys for replies.
