Razer device is not detected in Razer Synapse on a system running Windows 7

| Answer ID: 4042
This answer provides a step-by-step guide when Razer Synapse on Windows 7 cannot detect your Razer device.

Effective February 3, 2026, Razer Synapse 3 will no longer receive updates or support cloud services. After this date, cloud syncing of configurations across PCs using the same Razer ID will be disabled.

Note: Your installed devices will continue to be configurable in Razer Synapse 3. However, if you uninstall these devices completely, you will need to upgrade to Razer Synapse 4 to continue customization.

Download Razer Synapse 4 and migrate your existing Razer Synapse 3 profiles using the Profile Migration Tool to retain access to your configurations. See How to migrate your Razer Synapse 3 Profile to Razer Synapse 4 for instructions.

Applicable Software:

  • Razer Synapse 4
  • Razer Synapse 3

Razer Products use SHA-2 digital certificates for their drivers. If you are using a Windows 7 version that does not support SHA-2, the drivers for your device will not be installed correctly. To fix this issue, you need to upgrade your Windows 7 OS to Windows 10 or Windows 11. For instructions, see How to upgrade Razer Blade laptops to Windows 10.
