Moving from TeeChart 5.5 to TeeChart 5.0

OK, because of a contract agreement I have to make some components that I
created work with TeeChart 5 instead of TeeChart 5.5.  Or, everything has to
work with the TeeChart that ships with Delphi 5.

So, does anyone have a recepe for moving back to TeeChart 5 without
reinstalling Delphi 5?

Note: I've already removed TeeChart 5.5 from the system, I'm just having
trouble reinstalling TeeChart 5.0.
