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 was https://techpaul.wordpress.com/2011/07/18/cure-for-windows-update-error-66a/ failing to install. So, I clicked on the Start button > All Programs > http://www.personalcomputerfixes.com/general-errors/how-to-fix-windows-update-error-66a/ Windows Update > “View update history“. Sure enough, in the “Status” column, I saw a “failed”.. on an Update named “Security 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 code windows update 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 list). Step windows update error 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.
