After the software installs, a pop-up will likely appear: “Firmware update available.” Do not skip this. Click “Update.” Your mouse may become unresponsive for 30 seconds—this is normal. Do not unplug it.

Once the 85MB installer downloads, right-click the file and select “Run as administrator.” This ensures the mouse driver installs correctly in the Windows registry.

Navigate to the official Jertech support portal (www.jertech.com/support). Do not download from third-party “driver updater” websites. Look for the section labeled “Jertech Mouse Software Updated – Version 4.2.7.”
