|Go to "Control Panel > Folder Options > View" and put the blob in "Show hidden files, folders and drives". Apply/OK your way out and EXE file extensions will become visible. I always leave that set (far better) but you can undo it later if you wish.|
Use Windows Search for the file PPTVIEW.EXE and when you've found it right click the entry and jot down its location (full path). It might be worth going to Computer and following the path you jotted down to make sure you can find the PPTVIEW.EXE file (that gives confidence). Now repeat what was given in #1 but when using Browse use the location you jotted down in order to find the above EXE file.
You will need to do this using each power point file type you are interested in, including pps.
If the you can open a saved pps file when you double click it but not directly in email then the above associations are most likely already OK. In which case let us know what email program or service you are using.
Always pop back and let us know the outcome - thanks
