Version 5.4.9 of the package may be downloaded by clicking the link below. It is a self-extracting virus checked executable, which should be run to install the package. You are given the option to change the default installation folder (C:\AviaDBM), and the start menu folder (AviaDBM5). If the folders already exist, the items are updated. Please don't use any of the Windows "Program Files" folders because they cannot be accessed by AviaDBM, for instance to create GPS_USB.ini, and cause problems.
Some functions of the software are not operable until a licence has been obtained - see Registration
