Update Error66A Shutting down for the night, I noticed that my 64-bit Vista machine had “Updates ready to install” for the 3rd night in a row.. which is a pretty good clue that at least one Update https://techpaul.wordpress.com/2011/07/18/cure-for-windows-update-error-66a/ was failing to install. So, I clicked on the Start button > All Programs > Windows Update > “View update history“. Sure enough, in the “Status” column, I saw a “failed”.. on an Update named “Security http://discussions.virtualdr.com/showthread.php?257539-RESOLVED-Seven-Windows-Updates-Will-Not-Install Update for Microsoft .NET Framework 4 (KB2160841)” (also applies to KB2446708). So to find out what the problem was, I right-clicked > “View details”. What I am looking for is the “error code”. I saw that the windows update code in this case is 66A. Clicking “Get help with this error” led to several ‘solution’ suggestions – too many. So I will tell you the one that works for me. Step 1) Click Start > Control Panel > Programs and features. Step 2) Scroll down until you find Microsoft .NET Framework 4 Client Profile, and click on it, once, to “select” it (turn it blue), then click the Uninstall/Change menu button (above windows update error list). Step 3) A new window will open. Make sure the “Repair” radio button is selected, and press “next”. The automatic repair may take a few minutes to complete. Step 4) Return to Windows Update (as per Step 1) and make sure that only the “Security Update for Microsoft .NET Framework 4 (KB2160841) is checked, and click “Retry” or “Install Updates”. Now the Update should succeed. If it doesn’t, get the “standalone” installer by clicking here and choose either 32 (x86) or 64 bit (x64) to match your system. If that fails, I suggest calling Microsoft’s support number for free tech support (as this qualifies as a security issue) 1-866-PC-SAFETY. (That's right. Free. Microsoft provides free support for any safety/security related problem.) * Orig post: 4/17/11 Free offer: Folks, I just noticed that on buy.com, you can get a free 6 months of CA's (Computer Associates) antivirus + anti-spyware.. if you need some protection.

I click on install updates. All 7 fail. Errors are Code 2 and code 66a. I click on get help with this error and #4 shows up in red Troubleshoot problems with installed updates. This takes me to the "Fix it". I run the "Fix it" and is says found problem and fixed them. So I try to install the 7 updates again and all 7 fail. I try manually installing the updates and all fail. I turn off Microsoft security and try installing the updates. All fail. I get the same results with code 66a. Any help would be appreciated. If you need more info let me know.

What versions of .NET do you have installed? Win7 comes with .NET 3.5 by default. http://support.microsoft.com/kb/2507641/en-US If you installed .NET 4 and/or 4.5, you might want to clean them out first. See if the other Windows Updates go through, then
