Miscellaneous

I have to upgrade a bunch of client from NAV2004 Pro to Symantec AntiVirus Corporate Edition. I cannot find a way to do a silent uninstall if NAV2004. I tried the MSI /x{ProductGUI} with variuos /q switches but all I get is that uninstall must be ran from navsetup. Tried to run navsetup /s /v/x{} /qb but this did not do anythng. Tried to do a snapshot of the uninstall but that was a disater. I am trying to automate it through the companies login script. Any help would be appreciated

Cheers!
