We fully support the current release version of our software (see Supported Products Policy). We frequently help customers with questions on statistics, and hardware problems unrelated to our products.

Many software updates result from clients who share what they wish our software would do, and what new features would be nice to include. We also improve documentation and error handling based on support calls from researchers using our software.
GDM provides free ARM support only for the newest ARM release version. If you have ARM questions or problems, please install the newest release version before contacting GDM for support.

Screen-Sharing Support

GDM provides a method of computer screen sharing to provide support, based on the commercial TeamViewer application.
ARM Support Viewer (exe) shares your computer screen so an ARM support person can see the computer screen to help answer questions or solve a problem with GDM software on a PC. Contact your GDM support person, and tell them your ID and Password displayed on the support viewer so they can complete the connection.

Note: ARM includes an ARM Support Viewer link on the Help menu. You should only need to use this website link when having problems installing ARM, to display your computer screen during an install.

See Using the ARM Support Viewer (pdf) for more information
