I get this message when using the most recent eLicenser on the latest High Sierra - maybe this is linked to the export problems some users (including myself) have been having?
Hello, the cause of this message is the fact that eLicenser Control Center is a 32-bit program, whereas Apple encourages Developers to update their programs to 64-bit architecture.
We’re currently working on an update to make elicenser Control 64-bit.
Until then, please ignore that message, which should be displayed only once when the program is launched for the first time anyway.
