There can be more reasons which determine that you are not able to open the KEYCHAIN file (apart from the lack of the proper application installed).
First - the KEYCHAIN 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 KEYCHAIN 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 KEYCHAIN 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 KEYCHAIN file has not been completed and it cannot be opened properly).
