Where it says 'Another Version of this product is already installed' The Software installer needs to have an Autodetect built in to detect which of the current installed software item on the defining application is to be un-installed whenever the new application is to be installed insted of it.
The system up to now is still misleading to which of the correct application item is to be selected for to be uninstalled so that the newParagon application can easlily replace it.
