Update KB3004394 was the issue for me. Uninstall that and restart then attempt to use the diagnostic tool.

@minimumimpact Thank you for your post. You saved my day and my sanity.

Hi, thats interesting about UAC & that could be the difference between it working for some & not for others, i have two different User Accounts on my Windows 7 system, one is a standard user for guests & the other is an Admin account that is password protected, ill also add that i did turn off UAC notifications because its nagging is a right pain whenever i download or install software, its one off the downsides to Win 7

You sir are awesome, that fix was searched hard and you had the only correct answer I knew it was an update but so many updates went in on fresh installs it would have taken forever 1x1. You nailed it congrats. Microsoft's solution? Repair install or format. I did reinstall 3 x thinking maybe faulty ram but after that I knew it was an update issue.

Hey new user here just wanted to say thanks to everyone that contributed-most frustrating 3 hours ever. I'm a rookie-took me forever to get everything straight but all good now. Muchas gracias

It may just be that I'm not extremely computer-savvy, and so don't really know what I'm doing, but when I search through the control panel update uninstall window, I can't kind the particular update that's causing this issue. The weird thing is that I can still see it in my update history as having been a successful installation. What should I do about this?

I have a program from i0bits called uninstaller, and it lets me see each item that was in the update clearly. its a free program, and I guarantee you ...the best uninstaller I have ever used. Give it a try.

This program from IOBit may (or may not) be the greatest thing since sliced bread, but personally I wouldn't touch anything from IOBit with a twenty five foot barge pole.

To me, it's a simple matter of trust. YMMV. :)
