How to fix the 0x80070643 error

In case you are one of the users who have witnessed the 0x80070643 error, keep on reading. Woody Leonhard from InfoWorld has compiled a solution to fix the error.

First, make sure that the installation file is present on your system. Open File Manager and make it show hidden files by selecting View tab, check Show Hidden Files. Then go to the following location:

C:\Windows\SoftwareDistribution\Download\b0a5da1b24245bc4237166e09bae92da\


For 64-bit systems, the path should be:

C:\Windows\SoftwareDistribution\Download\c4a1b8896ce9fbfea96c1ee6890d52a5\windows10.0-kb3122947-x64.cab

There, a file windows10.0-kb3122947-x86.cab or windows10.0-kb3122947-x64.cab should be found. In case the file isn’t present, other solutions should be tried.

After you’re done, check if your system is 32-bit or 64-bit (unless you already know).

Then, right-click on the Start menu and select Command Prompt (admin).

If your system is 32-bit, copy and paste the following line in the command prompt and press Enter:

dism /online /add-package /packagepath:C:\Windows\SoftwareDistribution\Download\b0a5da1b24245bc4237166e09bae92da\windows10.0-kb3122947-x86.cab

If your system is 64-bit, do the same with the following line:

dism /online /add-package /packagepath:C:\Windows\SoftwareDistribution\Download\c4a1b8896ce9fbfea96c1ee6890d52a5\windows10.0-kb3122947-x64.cab

Now, the KB 3122947 patch should be properly installed. Reboot.
