Common registry item missing causing Windows Installer and SFC errors

article #826, updated 768 days ago

This is often missing:

HKLM\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing\Version

To fix it:

1. Navigate to C:\Windows\Servicing\Version and read the name of a subfolder. It will be named something like 6.1.7600.16385. That is your {TrustedInstaller ID}. Copy the name of that folder to the clipboard (and paste it in Notepad for safe keeping).
2. Find a subfolder in C:\Windows\WinSxS whose name starts with:

x86_microsoft-windows-servicingstack_31bf3856ad364e35_{TrustedInstaller ID} (32bit Windows)

amd64_microsoft-windows-servicingstack_31bf3856ad364e35_{TrustedInstaller ID} (64bit Windows)

Copy the name of that folder to the clipboard (and paste it in Notepad for safe keeping).

3. Create subkey “HKLM\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing\Version”. You will need to take ownership of “Component Based Servicing” then give yourself full access permissions before you can create the key.

4. In the new Version key, create an “expandable value” using the TrustedInstaller ID as its name and the complete path of the folder you identified in WinSxS as its value. Properly you should use %SystemRoot%\WinSxS\whatever instead of C:\Windows\WinSxS\whatever.
