Run Windows Installer & Safe Mode

To make Windows Installer work under safe mode, you need to create a registry entry for every type of safe mode you are logged in to.

    Safe Mode.
    Type this in a command prompt:


    REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\MSIServer" /VE /T REG_SZ /F /D "Service"

    and then

    net start msiserver

    ***********************************************************************

    This will start the Windows Installer Service.
    Safe Mode with Network


    REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\MSIServer" /VE /T REG_SZ /F /D "Service"

    and followed by

    net start msiserver

    This will start the Windows Installer Service.
