Windows 7: .NET updates fail to install with error 800B0100 and 80070308

.NET updates fail to install with error 800B0100 and 80070308

KB 2518869, KB2572077, KB2633873, KB2656356 repeatedly fail to install with errors 800B0100 and 80070308.

These four security patches have repeatedly failed to install since 23 March.
Win 7 SP1 was installed on 21 March 2012

I have run the Microsoft FixIt and the System Update Readiness Tool (KB947821) but no change.

Looking for any guidance on how to install these four updates.


Some background info...

Have you tried to install them manually instead of through Windows Update?

Yes - I manually downloaded and installed one of them and it made no difference.

I have also run the installer from Control Panel > System and Security >Windows Update but that also fails every time.

BTW - each time the PC is shut down it says it is installing 2 updates not 4. But that still always fails.

* Have you a System Restore point created PRIOR to this problem that you can roll back to?
See if this helps.

* Start > Control Panel > System & Security > Find & fix Problems >System Security > Fix problems with Windows Update.

If no joy you might run the
.NET Frameworks Cleanup Tool .NET Framework Cleanup Tool User's Guide - Aaron Stebner's WebLog - Site Home - MSDN Blogs
http://blogs.msdn.com/b/astebner/arc...8/8904493.aspx
for the appropriate version of .Net Framework


* Try to install again.
Always install one at a time.
Reboot on completion of each one.

I have an easier solution. In Windows Update, right-click on each update & select the Hide option. Then it doesn't bug you any more.

I know, I know, that's just asking for trouble. Well, I'm rather annoyed that I'm seeing this problem with:

(1) Security Update for Microsoft .NET Framework 4 on XP, Server 2003, Vista, Windows 7, Server 2008, Server 2008 R2 for x64 (KB2656368)

(2) Security Update for Microsoft .NET Framework 4 on XP, Server 2003, Vista, Windows 7, Server 2008, Server 2008 R2 for x64 (KB2686827)

(3) Update for Microsoft .NET Framework 4 on Windows XP, Windows Server 2003, Windows Vista, Windows 7, Windows Server 2008, Windows Server 2008 R2 for x64-based Systems (KB2468871)

My system (click the My System Specs button on any of my posts) is barely a couple of weeks old. A buddy of mine gave me -- I say, donated, free, gratis, it's good to have friends like that -- gave me this system & he installed the OS for me. I've just tweaked some of the cosmetic stuff within the system, customizing it very lightly. As far as I can tell, I have no applications that actually use .NET. Task Manager never shows any of those mscor* tasks running except after I've tried to install the above 3 mentioned updates. It is also annoying that when Windows Update does launch those .NET services as part of the update process, I have to go into Services and manually demote their Startup Type back to Manual when I also stop them.

My point is, this is a pretty fresh install. The only application I have ever encountered that explicitly required .NET (and specifically for which I installed .NET, which I did not have prior to that) was one to update the BIOS in my portable XM radio receiver. I ran that exactly one time about a year ago on my previous system (it was WXP) & never saw the mscor* things in Task Manager again after that. And I've never (2-3 weeks of usage) seen them here on Windows 7 except, like I say, when I have been trying unsuccessfully to get these updates installed. I have not installed the XM radio app on Windows 7 & don't foresee installing it unless XM comes up with some really really really compelling feature update to the radio. I'm not sure why my buddy included .NET in this install, but he did & you know how you're supposed to treat gift horses . . .

<<<Total sidetrack. When I composed this post, I wrote the letter W and the digit 7 side by side. Apparently, this web site promotes that abbreviation to the full wording Windows 7. It doesn't do that for WXP or WNT or W98 or W95 or . . . ?>>>

I found advice elsewhere to run sfc /verifyonly & then some string extractor to analyze CBS.log. (I'm thinking CBS doesn't stand for Columbia Broadcasting System here. Check Boot Sequence? Collect Basic Statistics? Cool Beaners, Sam?) The only file it flagged was explorer.exe & I gather from my other reading in these Forums that this is actually something of a false positive due to the fact that I have modified my Start Menu Orb.

I tried using Windows Update to install each update by itself, with intervening reboots. No joy.

There's a couple of other things I checked based on things I've read in these Forums but I don't remember them now & besides, the updates still wouldn't install.

So I don't see why I should troubleshoot something like this. This is practically a virgin install. The problem isn't mine. It's Microsoft's. They need to figure it out. And their advice to me to get these updates installed had better not involve any disabling, uninstalling, or other quasi-violent if not destructive actions on my part. My system is functioning perfectly & since it ain't broke, I ain't gonna break it, let alone try to fix it.

Like I say, none of the .NET executables runs on my system during normal usage. So what's my security exposure? I'm running the Microsoft Security Essentials as well as AVGFree. I'm not too worried. So I've hidden the updates. If Microsoft ever pushes out another .NET update, I will allow Windows Update exactly one chance to install it, and then if it fails like these have, it gets hidden, too. The updates listed above got the 3 strikes you're out treatment. Future updates get only one strike before being sent to the showers.

I tried a large range of fixes, none of which would resolve the issue.

I had just started z conversation with Microsoft support when the PC crashed never to reboot (lots of other posts on the forum about this) and so the problem was "resolved" by doing a complete new install.

Since then well over 150 updates have gone through including the ones that previously refused to load.

Personally I DO NOT recommend the complete reinstall as a solution.

Well here it is 5 months later. A couple of weeks ago, MS pushed out a boatload of updates, including a few to .NET. With some trepidation, I allowed them to go ahead & attempt to install. My expectation was that I had another batch of .NET updates that I would end up hiding.

Surprise surprise! They installed. Hmmmm......... I wonder if those hidden updates will install now. Well, I crossed my fingers & toes (which makes it hard to type, especially the toes) and unhid those old .NET updates that had failed months ago & tried to install them again.

More surprise surprise! They installed! I still had to demote a couple of Services back to Manual Start but that appears to be a pathological behavior typical of .NET.

Now I have an "Important" update to Security Essentials that refuses to install. I've hidden it. Daily updates to Security Essentials install no problem. But this one update published in late September fails repeatedly. Oh well. I'm sending it into long-term timeout. Bad boy! Maybe in a few months, MS will do something unadvertised during one of their updates & I will be seized with the inexplicable urge to try to unhide & install this update again. If it ever mysteriously transforms from failing to succeeding, like these 3 .NET updates, I'll be sure to let y'all know.
