How it works:
dUninstaller reads the section of the registry where installed applications are registered with Windows. Within these registry entries is an "uninstallstring" value that tells Windows (via Control Panel) how to uninstall the application. With any luck, there is ALSO a "quietuninstallstring" value, which allows for silent /automatic uninstall. THAT is where dUninstaller's usefulness comes into play. It reads the quietuninstallstring (if present) and executes that command. If the quietuninstallstring is NOT present, dUninstaller will pass the /quiet /noreboot parameters to MSI based installers, the /sp- /silent /noreboot parameters to Inno Setup based installers, and /S for all other installers when running the uninstall command, which should do the trick. Note sometimes using this method causes certain installers to throw an invalid parameter or similar error - though this has been rarely reported.
