When you open a .PPS or .PPT file that came as a mail attachment in Windows Mail or Windows Live Mail, you may see the Open / Cancel dialog box. When you select Open, the following error may be displayed. This may happen even though you have PowerPoint Viewer 2003 or 2007 installed. However, the same file may open correctly when saved to disk, and then viewed. Note that this problem does not occur if you have Microsoft Office or PowerPoint installed.

[Error Message]

This file does not have a program associated with it for performing this action. Create an association in the Set Associations control panel.

This error occurs if the Open command is missing for .PPS and/or .PPT file types. To resolve the problem, follow these steps:

    Hello again, the fix worked.. I went back again & checked the areas I supposedly changed & one still said open.. guess it didn’t take the first time. Sorry for the negative comment previously submitted.
    The fix works perfectly
    thank-you winhelponline :)

    As for many with these buggy regisrty tweaks, I could now open PPV from WLM, but not from Desktop!?

    FIXED!-
    Be sure and uninstall old PPV/reboot before continuing!

    1. FIRST install MS Word, Excell, PPV Compatibility Pack for Win 7 (X86, or x64)/reboot.
    http://www.microsoft.com/downloads/details.aspx?familyid=941b3470-3ae9-4aee-8f43-c6bb74cd1466&displaylang=en

    Now Install MS Word 2003 Pro (bought it relatively cheap on Ebay- Buy Now).
    I used freeware Process Explorer (Download Cnet, Options Replace TM/reboot), to disable Explorer during install- When requested to do so.

    Now do your MS updates/reboot “twice (any MS update!) & check for more…

    ENJOY!

    Scott :o)

    Great! a fix, precise and to the point. Windows Vista Home premium SP2 with MS 2007 Office with PowerPoint Viewer 2007 installed as the default program of choice to open .PPS and now it works for Windows Mail attachments directly thanks to MISTER RAMESH. THANK YOU Dale
