Uninstall Batch File

We are in the process of large scale deployment of our remote access tools in our company. We need to unistall two existing components before we go ahead with installing new tools. I want to be able to run a .bat file that will uninstall both programs and then will deploy a MSI of the new tools. I am not worried about the new tools installation but automating the uninstall process has been a pain in the neck.

I'm not at all an expert on batch files, but I'll provide the information that is needed, and wait for you experts out there to assist me if you can. I have the following uninstall strings,

"c:winnt\isuninst.exe" -y -f "c:\program files\PAL\Uninstl\DeIsL1.isu" -c "C:\Program Files\PAL\Uninstl\palunins.dll"

"C:\Program Files\InstallShield Installation Information\{EF964A78-078C-11D1-B7A7-0000C0134CE6}\Setup.exe" Uninstall

Are there any switches that I can use to complete silent uninstall?

Will appreciate your help.
