We at Gylling Data Management (GDM) create, market, and support ARM software for managing and summarizing agriculture research experiments.

  • ARM saves time creating trials, analyzing data, and producing the many reports required for successful and timely trial management.

  • ARM is a recognized and respected standard throughout the crop production and protection industry.

  • ARM is used by thousands of researchers in 80 countries worldwide (more than any other integrated research trial management software).

How can I move my ARM settings, validations lists, and studies to a new computer?

Before using your new PC, use "Migrate Studies and Settings to New Computer" in the Utilities menu of ARM 9.2014.x or newer to create a package containing personal lists, report sets, and ARM settings on the old computer. Then, deactivate the old PC, install and activate ARM on the new PC, and use 'Load Migration Package' to install this package on the new PC.
See Transferring ARM to a New Computer (pdf) for details.

What if I do not have access to my old computer to deactivate ARM?

If ARM was not deactivated on the old PC before the hardware became unavailable, GDM can manually deactivate the license. Please use Write to Us to explain why deactivation failed and provide your ARM serial number.
