Windows 7: 800B0100 error on 2 security updates, wont install

I ran Microsoft Fix It, that didnt help. I renamed the old folder(i forgot what it was called, i followed directions on how to do it from another post, it was a pretty standard procedure to try and fix it) that didnt help.

It is for updates:

Security Update for .NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 SP1 for x64-based Systems (KB2518869)
Download size: 14.2 MB

and


Security Update for Microsoft .NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 SP1 for x64-based Systems (KB2572077)
Download size: 11.0 MB

They are able to download but when i try to install them i get the error prompt saying they were not able to be installed. Thanks for any help.

WOW.. After uninstalling both

Microsoft Games for Windows - Live Redistributable
Microsoft Games for Windows Marketplace

Windows updater found 7 more updates that it wasnt finding before (some were even important system updates) Microsoft Games were installed. Unfortunatly it still didn't install the 2 Security updates mentioned in my original post, but the other 7 new updates were installed fine.

Seriously.... w t f

See if this helps.

* If no joy you might run the
.NET Framework Cleanup Tool User's Guide - Aaron Stebner's WebLog - Site Home - MSDN Blogs
for the appropriate version of .Net Framework
& try to install it again.
Reboot.

Windows Update error 800B0100

Error code 0x800B0100 when using Windows Update or Microsoft Update to install updates

ive done everything suggested except reinstalling NET framework, i refuse to do that. I guess ill just have to leave with these 2 security updates not being installed

It is recommended to install Security updates.

.NET Updates cause more problems than all the others put together.

Have you tried a Clean Boot, and installing hte updates from there?
How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

Not updating net framework leaves you buggy. and may leave security holes. Might want to fix it instead of passing on it.

Agreed - one of the major problems is that a later more critical update may not install, because it requires the earlier one that you ignore.

Those two updates were issued last year. One in July and one in October. Check to see if they're listed in your history as "Successful" or really missing. They might have been installed already.
