I tried updating Express to the 3.2.4.0 version and each time I tried the Garmin express update just totally deletes the garmin Express software from my pc. I have to re-install Garmin Express from the website and tried to update to 3.2.4.0 again multiple times and the installer just deletes the software from my pc. It also deleted the Basecamp software from my pc. I have Windows 7 professional operating system.
