[Windows] Win7 installation of Visual C + + Redistributable x64 failed

When you install Visual C + + redistributable x64 in Win7, you get stuck because Visual C + + Redistributable x64 requires Kb2999226,wusa.exe (Windows System Console application,Windows Update Standalone installer ) will extract the downloaded WINDOWS6.1-KB2999226-X64.MSU to the C packing directory

Opening the folder will find the Windows6.1-kb2999226-x64.xml file as follows:

 
 
<?xml version="1.0" encoding="utf-8"?>
<unattend xmlns="urn:schemas-microsoft-com:unattend">
    <servicing>
        <package action="install">
            <assemblyIdentity  name="Package_for_KB2999226" version="6.1.1.7" language="neutral" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35"/>
            <source location="%configsetroot%\Windows6.1-KB2999226-x64.CAB" />
        </package>
     </servicing>
</unattend>

The reason for the card owner is that the path to the package cannot be found, there is a <source/> node in the XML file, and its path is identified as <source location= "%configsetroot%\ Windows6.1-kb2999226-x64.cab "/>,%configsetroot% is a user environment variable, but does not exist by default, So Wusa.exe will not find Windows6.1-kb2999226-x64.cab.

Workaround:

Create configsetroot environment variable, open My computer in the address bar input%configsetroot%, enter, will jump to the environment variable set path, Copy the Windows6.1-kb2999226-x64.cab (extracted from the above mentioned Wusa.exe in a folder in the C packing directory) to the path.

Rerun the Setup program.
