Yet another possible (simple) solution that worked for me.

Launch the MSN Messenger (6.2) installation program. When you get to the error message, don’t click OK. Go to your start menu and open Messenger. Now all you have to do is Ctrl-Alt-Del and end task on the isntallation software. This causes to not uninstall the files that were previously installed.

If you can’t open Messenger after you closed it, try this other solution. When you get to the error message, copy paste the folder C:Program FilesMSN Messenger to MSN Messenger2 . Close the installation software with Ctrl-Alt-Del and rename the folder to MSN Messenger. Then create your own shortcuts.

It didn’t work on my computer with Messenger 7.0 beta but you can try it.

I’ll be damned, Now I can install 6.2 without any problems, but still can’t install 7.0 beta. Tip: don’t install beta versions!!!

Thanks bxnapkin your solution helped, well kinda….I did the ctrl+alt+dlt and then reran the installation and it installed then I logged on to msn but it wouldnt let me and error code 0x81000370 came up. I went on this site called msn-problems and they gave me something to download to fix the error and it worked. HURRAY FINALLY!!!!No more errors for a day or two.
