setup.exe: keep

[Michael D. Berger & Rosalie A. Clavez]

In looking at the list of items I can install, I see that one
of the options is "keep".  What does this mean?
I would like to execute this sequence:
1 - download a complete new version;
2 - backup the complete new version;
3 - delete my old version;
4 - install the new version.
Does the "keep" oprion intefere with this procedure?

Thanks,
Mike.
