Unable to Install WIndows Live Writer on XP SP3

I was using Windows Live Writer for sometime on XP SP2. After installing SP3, many programs stop working. One of them is the Windows Live Writer. I keep getting Windows Installer error and Windows Live Setup service errors in the event log.

It seems that when running Windows XP SP3 many people are having issues installing windows live applications using the windows live installer. After much googling I have come across a solution. This also solves issues that exist with the windows update service after installing SP3.

Essentially what you need to do is:

1. Download and run the Windows Live Installer Cleanup tool from:

2. Reboot

3. Click START>Run and type 'command' to load the console.

4. Type in:

regsvr32 wups2.dll

and press enter.

5. Type exit to leave the console

6. Download and run the windows live installer, it should now work perfectly.
