Clicking the "Advanced Options Installation" button on the welcome screen gives the user full control over the installation.
The first screen in the advanced installation allows the user to select into which folder the application should be installed. The ellipsis (...) buttons provide access to a tree view to quickly select the parent folder and type in the new subfolder to create.
DeployMaster will not ask whether the selected folder should be created. Most people will want to install a new application into a new folder.
The second step is the file associations.
