did you mean when press enter it is not going to the next cell?
did you check the tools-options- edit-move selection after enter

My "Enter" key is not working only in Excel; it works in other programs
including MS words. I already reinstalled the full MS Office package, however
it still doen't work. Please let me know how I can solve this problem.

Without "Enter" key, it is really hard to conduct any spreadsheet works.

Thanks.
