Windows Update problems busters
article #727, updated 746 days ago

Yet something newer than the below, the Windows Update Automated Troubleshooter:

Microsoft is now providing an interesting toolset for Windows Update issues on current operating systems:;en;3779&showpage=1

And another Fix-It:

And something to install, the SDK, which contains Windows Installer 4.5 and possibly 5.0 too:

The below are our previous methods, from the indefatigable Mike Hunsinger. It is best to try level 1, see if that fixes, go to level 2. Both of these are done in administrative command prompts.

Level 1.

  1. Stop services:
    net stop bits
    net stop wuauserv
    net stop appidsvc
    net stop cryptsvc
  2. Rename folders:
    ren %systemroot%\SoftwareDistribution SoftwareDistribution.bak
    ren %systemroot%\system32\catroot2 catroot2.bak
  3. Start services:
    net start bits
    net start wuauserv
    net start appidsvc
    net start cryptsvc
  4. If in Windows Vista or Server 2008 R1: bitsadmin /reset /allusers

Level 2.

  1. Stop services:
    net stop bits
    net stop wuauserv
    net stop appidsvc
    net stop cryptsvc
  2. Deletions:
    Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr*.dat"
  3. Registrations:
    cd /d %windir%\system32
    regsvr32.exe atl.dll
    regsvr32.exe urlmon.dll
    regsvr32.exe mshtml.dll
    regsvr32.exe shdocvw.dll
    regsvr32.exe browseui.dll
    regsvr32.exe jscript.dll
    regsvr32.exe vbscript.dll
    regsvr32.exe scrrun.dll
    regsvr32.exe msxml.dll
    regsvr32.exe msxml3.dll
    regsvr32.exe msxml6.dll
    regsvr32.exe actxprxy.dll
    regsvr32.exe softpub.dll
    regsvr32.exe wintrust.dll
    regsvr32.exe dssenh.dll
    regsvr32.exe rsaenh.dll
    regsvr32.exe gpkcsp.dll
    regsvr32.exe sccbase.dll
    regsvr32.exe slbcsp.dll
    regsvr32.exe cryptdlg.dll
    regsvr32.exe oleaut32.dll
    regsvr32.exe ole32.dll
    regsvr32.exe shell32.dll
    regsvr32.exe initpki.dll
    regsvr32.exe wuapi.dll
    regsvr32.exe wuaueng.dll
    regsvr32.exe wuaueng1.dll
    regsvr32.exe wucltui.dll
    regsvr32.exe wups.dll
    regsvr32.exe wups2.dll
    regsvr32.exe wuweb.dll
    regsvr32.exe qmgr.dll
    regsvr32.exe qmgrprxy.dll
    regsvr32.exe wucltux.dll
    regsvr32.exe muweb.dll
    regsvr32.exe wuwebv.dll
  4. Reset networking:
    netsh winsock reset
  5. Reconfigure proxy settings:
    • If on XP: proxycfg.exe -d
    • If not on XP: netsh winhttp reset proxy
  1. Start services:
    net start bits
    net start wuauserv
    net start appidsvc
    net start cryptsvc
  2. If in Windows Vista: bitsadmin /reset /allusers
  3. Install the latest Windows Update Agent.
  4. Reboot.

Common registry item missing causing Windows Installer and SFC errors
article #826, updated 852 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.

How to Fix Windows Installer
article #70, updated 2140 days ago

The below is older. Here is the latest from Microsoft, the “Program Install and Uninstall troubleshooter”:


The very best thing to do about Windows Installer problems, might just be this:

But you should also get the latest version of the Windows Installer.

The current version is 4.5. These are new installers, which appear to contain cleanup routines:

There is also a separate cleanup tool.  Sometimes you will have to reinstall applications and/or do other cleanup work if you use it.  For this reason Microsoft appears to have taken it down from its sites.  I was able to get it from here:

article #60, updated 3323 days ago

To fix those annoying popups, first try this:

In the registry:
see one folder, with a long code name; enter it.
There is an entry named CDCache; change the value to 0 (zero).

If that doesn’t work, try downloading these three files:

and save them in C:\MSOCache\All Users\90000409-6000-11D3-8CFE-0150048383C9.
