License code pac project

[Beno]

Use the last post in this thread to find out what version you have installed.

PAC Project Versions

You can tell which PAC Project is installed on your machine by going to Control Panel, Uninstall Programs, it tells you the exact version or versions installed on your PC there. I have multiple versions of PACProject installed and working on my PC at present [image] Hope this helps Paul

Once you know that, you can contact Support (support@opto22 dot com) and get them to help with the license.
