Windows Live Messenger Install Issues

I thought I’d try out the new Windows Live Messenger. I downloaded it and tried installing it but get an error message “Extracting File Failed. It is most likely caused by low memory (low disk space for swapping file) or corrupted Cabinet file.”

Another box shows it is extracting the file MsnMsgs.msi, but hangs up there.

I am running XP Pro SP2, have 1 GB RAM and 39 GB of Disk space. I’ve tried downloading it from several sources but nothing worked. Any ideas?
