32 or 64 bit?

Here is the file from my system32 folder on Windows 7 64 bit.

64 Bit . I replace the file and uninstalled and reinstalled KB2685813 and ran SFC /scannow 4 times. Here is what the output currently yields. See attached.

Not sure if I am replacing the dll file correctly is there a step by step guide that you suggest using?

Its pretty simple, you just extract the file I gave you from the zip, once extracted you right click on the file and click copy. Then go to C:\Windows\System32, right click and paste, when it asks you if you want to replace the file hit yes.

If you get permission denied let me know and I will give you a reg file to add the take owner ship command to the right click menu, after you take ownership of the file in the system32 folder you will be able to replace it

Do you have a Win 7 Pro SP 1 install disk ?

See if an offboot sfc /scannow will fix it.

Change the boot order and boot up with the disk - after pressing any key to boot from CD/DVD you may be presented with an inverse screen with an option to press F8

Having done that, select Safe Mode with Command Prompt where you'll be presented with a splash screen to select Repair your Computer.

Confirm or change the keyboard/currency then follow the prompts to navigate to the Recovery Environment and select Command Prompt.

At the prompt enter bcdedit |find "osdevice" and using whichever partition letter it gives, enter (assuming c) -

sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows

There is a space before each forward slash and that's a Pipe symbol before find.

This way sfc has an incorrupt volume to repair from.

Enter exit when done to close the command window, remove the disk then click on Restart to see if that has resolved, depending upon what sfc reports.

Repair install of windows 7 fixed the issue, but after the re install i was running windows update and now KB982670 will not install. It may have something to do with Microsoft.NET i searched for this in programs and features and could not find it, tried to do an install of the current version of microsft.NET and would error out. Windows Error code 643.

also will not let me install the current version of internet explorer.

This MS article may help with that http://support.microsoft.com/en-us/kb/976982

What error code are you getting for the failed IE Windows Update ?

derrick.m.weiss · « **Reply #13 on:** March 30, 2015, 07:02:42 am »

Solved installed Microsoft security essentials, and then it allowed me to install the upgrade.

Not sure how that would have worked unless it was Windows Defender that was blocking as MSE turns that off.

derrick.m.weiss · « **Reply #15 on:** March 30, 2015, 07:34:26 am »

also ran a fix it tool. maybe that's actually what fixed it.
