A computing device for initiating trial use of a software, the computing device comprising:

• a memory;
• a processor communicatively coupled to the memory, where the processor is configured to perform
• displaying on a display coupled to a computing device at least two trial software icons as part of a messaging window, the messaging window is at least one an email program, a text messaging program, and a web-browser program, each trial software icon representing a trial software application that is not currently installed on the computing device, with each trial software icon representing distinct and separate versions of the trial software application for an identical application;
• based on moving, using drag-and-drop, an object representing a file attachment in the messaging window to the trial software icon, automatically performing installing the trial software application on the computing device, launching the trial software application after installation thereof;
• and
• opening the file attachment using the trial software application for viewing on the display, wherein based on moving the object representing the file attachment includes moving, as a single drag-and-drop action, the object representing the file attachment to two trial software icons positioned adjacent to each other, and wherein the automatically performing further includes:
• installing a first version of the trial software application and a second version of the trial software application on the computing device;
• launching the first version of the trial software application and the second version of the trial software application after installation thereof:
• opening the file attachment in both the first version of the trial software application and the second version of the trial software application to enable side-by-side comparison with the first version and the second version of the trial software application, wherein the two trial software icons behave as a “joint” or “composite” trial software icon to permit a quick side-by-side comparison by a single drag-and-drop action;
• and
• in response to that one of the trial software applications is selected, automatically uninstalling all the trial software applications that were not selected.
