Msiexec.exe file corrupted RRS feed

  • Question

  • Hi,

    I can't install any files or Windows Update. The Windows Install file (Msiexec.exe) is 0 bytes. It doesn't let me install new software or updates in Windows. I have Windows 7 SP1, x64.

    Is there a way to obtain this file? And check if any files/registers related are not corrupted?

    I already ran

    sfc /scannow

    Dism /Online /Cleanup-Image /scanHealth

    And the Windows Update Troubleshooter  Windows6.1-KB947821-v34-x64

    Thank you

  • Hi,

    Please try the following to repair the Windows Installer service on a 64-bit OS:

    1. Click on the Start menu, choose Run, type cmd and click OK
    2. Run this command: %windir%\system32\msiexec.exe /unregister
    3. Run this command: %windir%\syswow64\msiexec.exe /unregister
    4. Run this command: %windir%\system32\msiexec.exe /regserver
    5. Run this command: %windir%\syswow64\msiexec.exe /regserver
    6. Restart the computer and check the symptom.

  • Try cmd,type: msiexec /?  a new window should show installer defaults..To reset,go to run,type:  msiexec /uninstall

    then return to run,type:  msiexec /regserver   After a pc start,installer should be active,to set more defaults,in run or cmd,type:  services.msc  in msc,scroll down to installer,double click,set to Auto start,Start service,exit,do same with Win Modules,exit msc when thru..Win trouble shooters are maybe ok,but in this error(s),you need to install the download. windowsupdateagent-7.6-x86  get this from Microsoft...

  • Thanks for the answer, but it didn't work. It said: msiexec is not a valid file.

  • I ran the Install and Uninstall utility several times, to uninstall several programs that I had already uninstalled. An somehow it worked. I let me ran and install updates in Windows and other programs.
    I think it was after cleaning the installation of itunes.

    Thank you for your support.
