I no longer sell the desktop version of Diamond Scheduler. Please see the email sent out to all customers in November 2021:  http://www.cactusware.com/legacy

As a previous user of Diamond Scheduler, you do have an option. If you purchase a year’s license for the new web-based version of Diamond Scheduler and find that the desktop version has features that you need not yet available in the web version, I can extend your desktop license for the same period of time as your new web version license. However, be sure to email me at [email protected] to receive a discount code which will keep the price of the program at $99/year. Include the original purchaser’s name and email address, along with your desktop license key. That key can be found in the desktop program’s Help menu > Check Status of Subscription.
