This is not a concern just a query!
I have had this warning for some time, I was not concerned as the system does not have Microsoft Office Project 2013.
Warning: Update kb3101506 (id: 7ff19d18-bb37-4abd-812d-71b5342c93c2) not found.
If this is seen by wsus during downloading that "Project is not there" (in this case update generator would not download the update) then why would it be reported as missing when running wsus installer?
If wsus UpdateGenerator does not detect "Project" as not being there (in this case it would download the update), can you tell me why this is reported as missing?
Does wsus UpdateInstaller (detect) "Microsoft Office Project 2013" as being there?
Or is it assumed because office 2013 is installed?
This is a 64 bit WIN10 home system.
