Answering my own question . . . I did find it with Google after a little more searhing . . . I should be able to run MSIEXEC.EXE -I{app_guid} where app guid is the guid assigned to the app I want to uninstall.

>I'd like to be able to programmatically uninstall the previous version of my application from VFP. This is a side-by-side install and once the new version is installed and certain update tasks are performed, I'd like to launch the uninstall program just as if I'd gone to the Add/Remove Programs control panel applet and clicked Remove. I've been Googling for this, but no luck, yet. Anyone done this before?
