How would I perform a SILENT UNINSTALL?

When sending a silent install to workstations that have a prior version I end up with two versions on the same computer in Add/Remove Programs. (Installing 11.033 to a computer with 10.014)

In brief to Answer your query, If you look at registry location detailed below you may find an entry for your app Like:
Location: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
e.g WinRAR archiver and look for a entry: UninstallString it may be in the format: C:\Program Files\WinRAR\uninstall.exe run this command on the command prompt to uninstall. If its an MSI investigate upgrading the earlier version to the v11.033.

  • Try out this tool i put together. It'll make finding the uninstall keys easy.

You need to specify if you are using an MSI installer. If yes, you might need to add the UpgradeCode in your MSI package, otherwise if it´s a non-MSI, you might end up with a script uninstalling the old version prior to installing your new version.
