Silently uninstalling Visio 5 and Visio 2000

[Michael Egan]

I am trying to create silent uninstall scripts for Visio 5
and Visio 2000. I have a couple of questions:

How do I uninstall Visio 5 from a command line?

How do I uninstall custom setups of Visio 2000 from a
command line?

And, how do I do each of the above silently (quietly)?

Thanks,
Michael
