Eureka Messenger 4 software delivers secure and private messaging and unlimited file transfers over the internet.
This application no longer requires the VB Runtimes, but this new version 4 is not compatible with the previous windows version.
Installation:
Actually there is no install for this application. You can run it right where you unzipped it, or copy the files unzipped wherever you want them.
If there is a firewall on either machine, some configuration may be required in order to make a connection.
The program has a Help file to guide you on how it works, although it is simple enough to run without much assistance.
You probably need to issue a chmod +x messenger before it can run. On some linux systems you may also need to issue a chmod +755 messenger.
