Microsoft Windows 10 Support ended on October 14, 2025
This means that effective October 14, 2025, GDM will no longer support ARM software on Windows 10 computers. For more information from Microsoft on this change, see: End of support for Windows 10 | Microsoft Windows
The word 'support' includes:
- Questions or problems with GDM programs on a Windows 10 computer.
- Attempting to send or receive any files (ARM, Word, Excel, PDF, etc) on a Windows 10 computer.
- Installing GDM software on a Windows 10 computer.
- Installing any software updates on a Windows 10 computer.
Note that ARM software will continue to operate on a Windows 10 computer, but any technical issues cannot be resolved by GDM support.
Windows 10 is 10 years old, so it cannot adequately support or protect modern computer hardware and software. GDM software uses Microsoft tools, and Microsoft only supports these tools when running on supported operating systems.
When upgrading from Windows 10 to 11, we recommend following the same steps for Migrating Studies and Settings to a New Computer. This ensures that your Favorites lists, report sets, editor views, etc. made within ARM are preserved through the upgrade process.
Take ARM to the field with ARM Mobile
ARM Mobile is a mobile app for taking notes in the field on iOS or Android devices.
Download ARM Mobile here: https://mobile.gdmdata.com/armmobilev7
ARM Mobile facilitates the core principles for quality research:
- On-site data entry
- Record assessments consistently across dates and locations
- Review data on-site prior to leaving – only quality/correct data points count in research
- Data transfer occurs in a professional manner – not transcribed from paper to computer, and not copied and pasted from file to file

Notice Regarding Windows Arm-Based Devices and 32-Bit Compatibility
We are aware of recent changes in Microsoft’s support for 32-bit applications on Arm-based Windows devices (such as the Surface Pro X or newer “Copilot+” PCs). These changes may affect the ability to run certain applications, including 32-bit software not compiled for Arm64 architecture.
To clarify: Our software, ARM, is a 32-bit Windows application. The term “Arm” used by Microsoft refers to a type of processor architecture, not our product. While no issues have been reported to date, we are actively monitoring compatibility on newer Arm-based Windows systems.
If you are using a device with an Arm-based processor and encounter warnings or issues when launching our software, please contact us. We are committed to ensuring continued support and will provide updates as needed.
How to check your processor type:
Go to Start > Settings > System > About, then look under Device Specifications for “System type.” If it says ARM-based processor or Arm64-based system, your device may be affected by these changes.
