Why does the Windows Installer no longer work in Windows XP?

Windows Installer on Windows XP has stopped. I can’t start it, no matter what I do. Any suggestions?

    Hello, most times it will give you an error/reason why it is not starting.  Have you gotten any error?  if you have, which error is it? 

    I would say you could try running the system file checker command.  What this command does is check the files on your system with the original files.  If there is a file missing it will reinstall it.  This is how you use it:

    -- click on start
    -- type cmd
    -- this open command prompt
    -- type the following command:

    sfc /scannow

    Keep your windows xp installation disk handy.

        Hello, you can still run the commands shown in previous post without installation disc. Have you tried doing the following? Make sure to log in with administrator account:

        -- click on start
        -- click on run
        -- type cmd, once command prompt opens, type the following commands and press enter after each one:

        net stop server
        net start server

        Have you tried installing the most recent verssion of windows installer?

    If nothing works, use system restore, and go back to a system restore point when it was working.

    First thing you should try is re-registering the Installer service.

    1. click Start > Run (Windowskey + R)
    2. type "msiexec /unregister" and click ok
    3. open another run dialog and enter "msiexec /regserver" and click ok

    Then try starting the service again.

    Other then that please open up the Event Viewer, look for the entry related to the Windows Installer (or msiexec) and give us the exact error code and description.
    Start > Control Panel > Performance and Maintenance > Administrative Tools
