When using Windows Live Mail on Windows 7 you might experience the problem with opening Power point files (.pps). Once you try to open an .pps attachment in Windows Live Mail you might receive the following error message:
This file does not have a program associated with it for performaing this action. Please install a program, or if one is already installed, create an association in the Default Programs control panel
This usually happens if you have a Power Point viewer installed instead of Power Point and it mostly happens when you try to open files from Windows Mail. Opening .pps files from other locations works normally though.
Solution:
To fix these issue, four registry entries have to be changes for both .pps and .ppt files.
