PPS will not open in Windows Live Mail

I am the IT guy for my community and have come upon a problem I cannot fix. I know this IS the place for correct answers.

Problem: A user using Windows Live Mail is unable to open .pps files received with WLM. He gets an error message saying there is no file association for files with that extension.

BUT... he does have Microsoft Power Point Viewer installed and it IS the default program for .pps, .ppt and such programs.

He also uses embarqmail webmail (just for .pps emails) because his web based email will allow him to open power point presentations.

I know he has his defaults set correctly but they just won't work. He wants to use Windows Live Mail exclusively for his email but until this problem is resolved, he can't.

OK... you have the problem.... Who will be first with the correct solution?

Hello rhlhamlet,
How are you keeping, well i hope.
I found this, not too sure if it will be of use, but worth a read i think.

Unable to Open .PPS attachments directly from Windows Mail or Windows Live Mail - The Winhelponline Blog

Hope this helps, good luck and post your results.

Thanks, Stoney.... I was hoping there was a way to doing it without editing the regedit but if that's my only option, I'll just have to do it.

If you wait a bit, somebody may come up with an easier way of doing it, but what ever happens, don't forget to back up the registry.
The only time i didn't back it up was the only time i messed it up lol.
