Silent Uninstall using CLI

[hercules33]

Hi Everyone

I'm trying to uninstall existing application (created by setup factory) when installing a new one, by using the following code:

-- Uninstall previous version
Shell.Execute("C:\\Uninstall.exe","open","/U:c:\\uninstall.xml /S");

The uninstall appears but not in silent mode

Any ideas?

Thanks

Is the option Uninstall > Settings > Allow silent uninstall enabled?
