I have a Windows 10 upgrade that is behaving abnormally when it does automatic updates. This is also causing me an issue with installing Office 2010.

I have several automatic updates that are downloading and installing correctly. However, 3 fail without giving any details that I can use to determine the issue. I have downloaded them directly from the catalog and they try to install, but fail without an error message. The updates are KB3103688, KB3106932, and KB3105213.

What I think is related is my installation of Microsoft Office 2010. When the installer runs, it gets so far and then gives me the following error

"Error 1935: An error occurred during the installation of assembly component {A75F2217-AD54-3EA6-AE14-F255F8660531} HRESULT: 0x80071A91". After rollback, this is followed by a "Fatal error during installation."

I also get an intermittent error regarding installation of the 2.5 and 3.5 frameworks, of which I do not have the text at this moment. I have tried to install the frameworks, as well as the 4.0 and 4.5, but it tells me they are already installed. However, I cannot see them in my installed applications - I can only see 1.1.

I am running Windows 10 Pro on an i3, and I have nearly a TB free on the hard drive. 64 bit.

  • Provide those specific error messages – Ramhound Nov 29 '15 at 2:40
  • @Ramhound he already posed the error. I highlighted it for you ;) – magicandre1981 Nov 30 '15 at 5:32
  • have you tried my steps? Do the updates now work fine? – magicandre1981 Dec 5 '15 at 8:44

You get the error 0x80071A91 which means ERROR_RM_NOT_ACTIVE. Open Explorer, delete all files from C:\Windows\System32\config\TxR (make sure hidden files are shown in Explorer), now open a cmd.exe as Admin and run this command:

fsutil resource setautoreset true C:\

Now reboot Windows and after the reboot, try to install Office 2010 again.
