To correctly execute Cantax T1, your computer system must have the following:

Dual Core processor (Quad Core is recommended)

  • Windows 7 SP1 (32-bit and 64-bit) except for Starter and Home Editions*
    End of support: Microsoft will stop supporting Windows 7 and Windows Server 2008 R2 SP1 in January 2020. Since it is our policy to align our support of operating systems with software vendors, take note that the versions of our software applications that will be released starting in November 2019 will no longer support Windows 7 and Windows Server 2008 R2 SP1.
  • Windows 8.1 (32-bit and 64-bit) except for Basic Edition*

  • Windows Server 2008 R2 SP1
  • Windows Server 2012 SP1 and R2

* For more information on the different Windows Editions, and their respective minimum requirements, consult the Microsoft Web site:
For Windows 7 For Windows 8.1 For Windows 10

Note: RAM requirements are highly dependent on the operating system used. Please refer to the documentation provided with your operating system for minimum and recommended RAM requirements.

Important: While supported, Windows 7 SP1 and Windows Server 2008 R2 SP1 do not have SMB 3.0 encryption for data in transit and are not recommended system requirements for this product. We are strongly recommending that all customers enable the enhanced security measures available in Windows 8.1 or higher operating system, including SMB 3.0 encryption for data in transit. Since the configuration of SMB 3.0 is explicit, please consult this Microsoft article to proceed with its configuration.
