That's helpful, but sparks a couple more questions. First, how do I call the vbscript from WPI. I've never actually written a stand-alone vbscript. I assume I would just save it as a specific filetype, drop it in the Install folder, and point the WPI command to that file. Is that close? Secondly, since getAntiVirusProduct() will return the name of the product and I have a command that will use that name to call the uninstaller from the command line, is there a way to use what is returned by getAntiVirusProduct() in a second command? Is that clear? Can I run a command with getAntiVirusProduct(), store that result, and then use it in the next command that runs my uninstaller?
