What else may cause problems?

There can be more reasons which determine that you are not able to open the P7S file (apart from the lack of the proper application installed).
First - the P7S file may be incorrectly linked (associated) with the application installed to support it. In this case, you need to change this link by yourself. To do this, right-click on the P7S file # that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the P7S file should be solved forever.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version, or download it again from the same source as before (maybe for some reason in the previous session the download of the P7S file has not been completed and it cannot be opened properly).
