Installed PP Viewer 2007 on machine using Windows XP; use Outlook Express for email. Any .pps file I receive by email refuses to play automatically. The message says I am to go to Folder Options and add an association for the file. I have done that 36 (well, nearly) times. No go.

If I save the .pps file, then play it, PP Viewer works just fine.

Help! :hotbounce

Click OK and/or Close until you're back in Windows Explorer.
