What else may cause problems?

There can be more reasons which determine that you are not able to open the SUM file (apart from the lack of the proper application installed).

First - the SUM file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the SUM 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 SUM file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the SUM file has not been completed and it cannot be opened properly).
