Make Windows Installer work under 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.

  1. 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.

  2. 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.
