The following shows the contents of the USB key that I installed the suite on. Since there is an autorun file present, this could be your problem. On OSes that permit USB devices to autorun on insertion, this will cause the application to run automatically (Windows 7 doesn't have this feature enabled for security reasons). On an internal drive, this file might be executed each time the drive is first accessed. Delete
Autorun.inf, close the main application window and then delete the folders and files. The ones to delete are shown below (delete all of these).
