Supported Platforms - Choose the platform that's right for you, not us.
One of the key values that FirstClass provides to our customers is flexibility and choice when it comes to supported computing platforms. We're not in the business of selling computer hardware or operating systems so we have no reason to force our customers to run a particular operating system or to upgrade their infrastructure just to run our latest software.
This means that you can choose to run FirstClass on the platform that best suits your environment – Windows, Mac OS X, or Linux. The FirstClass server runs identically on all three platforms.
FirstClass also provides tremendous choice at the user level with Windows, Mac OS X and Linux "thin client" software options available as well as a range of web user interfaces to fit a wide variety of browser-based environments. The FirstClass Client works the same way on all supported operating systems, so there are no "second-class" users. Imagine the benefit of being able to support the Windows, Mac, and Linux users within your organization with a consistent, identical suite of services.
NOTE: We strongly recommend that any new hardware purchased for FirstClass be able to run a 64 bit operating system as FirstClass 10 will require a 64 bit architecture.
