D5 pro W2000 administrator<->user error 432

I have the same classical problem using Delphi 5 as user on W2000.
No components except TFrame.

I know that I have to install Registery only as user ... bun I can't.

When I run setup as user I have : error 432 setup has detected
uninstallshield in use. If I run it as administrator it doesn't fix the
problem.

Thanks in advance,
regards.
