Installing Diamond Scheduler on Multiple Computers
You can have the program installed on up to three computers simultaneously. If you want to move one of those installations to a different computer, you can do that also using the following instructions.
To download the setup file and instructions on the new computer, you can download the current version at http://www.cactusware.com/file-downloads. You’ll also find installation instructions there.
If you already have the program installed on one computer, you might want to copy and paste your current license key to use on the new computer, just in case you didn’t keep the original email with the license.
You can selected the license key then copy it for use on the new computer
If you’re moving a license, rather than simply installing the program on a different computer, go to the Help menu and Deactivate this Installation.

You will then be able to install the program on a different computer and use your license key that you kept.
