“flxActAppActivationSend - (0,0,0)” error when activating licence

This error indicates your licence code isn't installed correctly. Within Geneious, try Help→Install FLEXnet, and once its installed put your licence details in under Help→Activate License. You need to have admin rights on your computer to install FLEXNet and Geneious.

If you are on a Mac, and you still get this error, go to the terminal window and type the following (exactly as below all on one line):
sudo mkdir -p "/Library/Preferences/FLEXnet Publisher" ; sudo chmod 777 "/Library/Preferences/FLEXnet Publisher"

If this doesn’t fix the error then it is possible that you have the Adobe tools installed and they've already created these directories but with the wrong permissions so do the following in the terminal:

sudo chmod 777 "/Library/Preferences/FLEXnet Publisher/FLEXnet"

That should set up the permissions for Flexnet properly and enable you to activate your licence.

    Hello, I have stumbled on the same problem and error. After a lot of experimenting, I found that Windows has messed up the ownership and permissions to some folders on my PC.
    Here is the solution.
    1. Uninstall any Java Runtime Environment you might have.
    2. Reinstall Geneious with antivirus and firewall switched off.
    3. Ensure that the Windows account you are using (even when it is Admin) have the ownership and permissions to Geneious folder as well as C:\ProgramData\FLEXnet
