Make Windows Installer work in Safe Mode

To make windows installer to work under safe mode you need to create a registry entry for every type of safe mode you are login into:

Safe Mode:

Type this in a command prompt and hit Enter:

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

Then start the Windows Installer service by typing net start msiserver

Safe Mode with Network:

Type this in a command prompt and hit Enter:

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

Then start the Windows Installer service by typing net start msiserver.

    Oops, space in the wrong place. Thanks for pointing it out. Corrected.

    That and the curly quotes.
    Commands should go in a code block rather than a quote to preserve the syntax. Or you could copy and paste from the post

    You can also add the keys manually, from the registry editor.
