My update for c++ kb2467173 fails every time with the error code 64c. I would greatly appreciate any help I can receive on this. Windows 7 ultimate

See if there is anything in the Temp folder that is causing the installation failure.

With all programs and browsers being closed, clear the Temp folder by clicking the Start orb > in the Search programs and files field type in %temp%
Open the Temp folder.
Move all contents of Temp to the Recycle Bin for now.

( The contents of Temp should not be needed if the system has been restarted after the installation of software, updates, hardware drivers, etc. )


Try to install KB2467173 now.

No, it's not "normal" to see that Windows Installer message when uninstalling/installing software.
There could be several reasons for it but the most prevalent ones are that there is a great deal of "stuff" in your User Account's temp folder ( Users\<YourUserAccountName>\AppData\Local\Temp ), software is being installed and then the installation file is deleted prior to a required restart of the system, there has been a sizable amount of software installed/uninstalled that has caused some type of corruption in the local installation database (Windows\Installer), or, there's an incorrect setting(s) in the registry.

Microsoft use to offer the Windows Installer Cleanup Utility to resolve this error but it caused issues with the latest Versions of Office so it was pulled. There is a Fixit that may resolve this error when installing MS software -

You receive an "Error 1606" error message when you try to install or remove a Microsoft program

If you can, suggest checking the registry entries that are shown in the KB article for Windows 7 to see if your system's settings are the same, Matt. If a "registry cleaner" has been previously used, those settings may have been changed. If the settings differ, either make the necessary edits manually or run the Fixit.

Please, backup the registry keys shown in the KB article before doing any registry editing -

You're mowst welcome, Matt. We're glad to hear the installer issue has been resolved.

Try this:

You will find the download link for the x64 version of the Microsoft Visual C++ 2010 RTM Redistributable MFC Security Update in the same download page, you will need to click on vcredist_x64.exe size 9.8 MB.
Microsoft Visual C++ 2010 RTM Redistributable MFC Security Update
Download details: Microsoft Visual C++ 2010 RTM Redistributable MFC Security Update

The OP's update issues have been resolved.

FWIW, x64 systems also must install vcredist_x86.exe, too.
