MMC cannot open the file *.msc

"MMC cannot open the file c:\windows\system32\secpol.msc

This may be because the file does not exist, is not an MMC console, or was created by a later version of MMC.This may also be because you do not have sufficient privileges to access the file"

is the error I receive when trying to "double click" to open any .msc file. I also receive it when trying to right click "My Computer" and then click "Manage".

I'm stumped, y'all. :confused: I am seasoned with over 13 years help desk support and Networking, and I'm Security+ Certified from CompTIA. So I searched the internet and found this link. It talks about WindowsXP and links to this page, which in turn talks about
KB842773. So I searched that and found it on It speaks to several operating systems, but not Windows7, and talks about updating BITS to version 2 and HTTP Services to version 5.1. I have not checked, but also don't have the time to look up every single KB article that Windows Update has installed. I did look in Programs and Features, Installed Programs, and Show Installed Updates to see if anything was listed about BITS or HTTP Services. It was not.
I *can* run .msc's if I WIN-R>mmc then add/remove snap-in. But that is the *only* way to run any .msc.

Windows 7 Ultimate 6.1.7600
Intel "Wolfdale" E8400 @ 3.0 GHz
6 Gb RAM
4.41 Tb HDD space, with approx. 2.3 Tb free,
C:\ Drive has about 196 Gb free
1 drive is IDE, but it is not C:\ the rest, including C:\ are SATA @ 3Gb/s
System Protection/Restore turned off on all drives except C:\
virtual memory or page file is system managed

That's just some system specs that may or may not have anything to do with this. Like I say, I'm stumped. I really hope someone can help! Need more info just ask!
