Failure Installing KB2556532

Used the System Readiness Tool, rebooted and then tried the update again. Failed with same error which tells me absolutely nothing! Any ideas???

I need to see the log....

If you don't do anything else, you might try hiding the update to keep it from downloading and trying to install again. But you are still having problem when your system tries to verify the update status or access the folder containing the downloaded update...

Also, even though I think the Fixit did this already, you might try renaming the SoftwareDistribution folder and allow it to be rebuilt. There appears to be corruption somewhere in your system.

If we are talking about the same log (please give me a log file name) all it gives is the error. I have already hidden the update but will rename the folder and see if that helps. If not I may not bother anymore as it has already taken enough of everyone's time.

The update readiness utility writes a log to the Windows\Logs\CBS folder called Checksur.log. I need that one to see if there were any errors repaired, or any that could not be repaired.

Other than my last suggestions, if the log shows no errors, I am out of any ideas for now.

Sorry I haven't been able to figure out your problem, but I would like to bring up some points just in case.

I have searched your Update log for any Windows Security updates and can only find the one with the error. This might be because you restarted the log during the fixit process and the prior ones do not show, or you are not getting the security updates.

The problematic update concerns a denial of service attack with reference to Remote Desktop. There is always a chance the update is not working because something is intentionally blocking it. Perhaps a good run with an anti-virus might see something, but it would be a very good idea to make sure the Security updates are being implemented. Since you have other systems, you can check against those. The Update history will show "Security Update for Microsoft Windows" so hopefully the other ones are still installing. If not, try hiding KB2556532 and see if those updates resume.

Had this same issue with one of my machines. It appears two NET Framework updates and a Windows 7 update were not installing. Oddly they are all running the same version of Windows (32-bit 86x), but this isn't something new for me on this particular machine. I generally find I need to install the updates manually, one by one restarting after each completes, and perhaps in a particular order.

For me, the fix was just to click on the "More info" link that appears in Windows Update when your install fails and manually update. I started with one of the NET Framework updates. Reboot and then just refresh Windows Update a few times. Very odd.

This is a look at my ReportingEvents.log

I ran Windows Hotfix and then noticed this message... obviously I'm cutting off the rest.
Installation Successful: Windows successfully installed the following update: Hotfix for Windows (KB947821)
(I then Rebooted)
Windows Update Client successfully detected 3 updates. (closed out Windows Update)
Windows Update Client successfully detected 3 updates. (closed out Windows Update again)
Windows Update Client successfully detected 2 updates. (Came back in and one of the updates was gone)...

basically rinse and repeat. Again, all I was doing was selecting "More info" link that appears in Windows Update when your install fails and manually download and install. Make sure you reboot after each individual install.

Sounds like this isn't going to help the original poster but I hope someone else.

I've "hidden" the failed update and will run a anti malware on the mahine just to se what I get. Doubt it will be an issue but you never know....if not I'll continue to lok into it while leaving it hidden if all else fails! Tried manually installing but got the same error message!!

I wrote a reply with a solution yesterday, but it does not seem to have made it to the forum yet. I believe there is a problem with the digital signatures of the two files. Windows Update checks for the signature and so the updates did not complete. When attempting to do a manual update (after downloading the file), the driver signature check that is enabled in a default W7 install prevented the update from completing.

Essentially the solution was based on disabling the signature check (CAUTION) for the manual install. Details are in the original reply. I would not be surprised if updated versions show up on Windows Update.

How do you disable the signatures for the update? Did not see your reply that has these instructions.
