This version is only adapted for Windows Home Edition users, meaning the working directory is adjusted to the OS being used. Everything else is the same as in version 6.5, and of course it also works on all other 64-bit Windows operating systems.
If you are using an older version, V6.4 or earlier, when launching V6.5 or 6.5a you must delete the settings.ini and aprs_settings.ini files or rename them, because the new versions use a modified structure of these INI files and the program will not function correctly if they remain in the working directory.
Versions 6.5 and 6.5a use the same INI files, so deleting/renaming them is not necessary.
