I downloaded from official site and installed latest version of Gammu for windows. The set-up runs just fine like any other exe I have ever installed.
Then, when I try to call the command as instructed in the official guide I get this message: (alternative)
I've tried anything but it's always the same.
All of the other similar "win32 not a valid application" questions are related to self-made applications or programming in general: I haven't found a similar problem related to gammu in the whole web, except for a very old case from seven years ago which suggest to downgrade, which of course I can't do.
any suggestion to this problem? anyone had a similar one
