I have an InstallScript MSI project for which I have disabled the upgrade. As such, when someone tries to upgrade it, the dialog pops up: "Anothe version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel. {G-U-I-D}"
I want to give a title for this dialog as it is blank and does not go with the other pop-up dialogs of the installer. Aslo, is there a way I can disable the main installer 'Cancel' button while this dialog is in the foreground?
