I just found I had the similar problem when running my "PS"tools, I ran psinfo on a machine the other day and it came back with 8.6.... I went through all the work to get on the machine and check it and eveyrthing was fine. I checked my machine and it was the same problem. I just figured it was a problem with Mcafee since I used two different instalation packs for the different machines. I am glad I am not alone with the issue.
