The Corsair M90 Gaming Mouse driver and configuration software help Windows recognize the mouse’s programmable features and let you tailor its controls to your games. Beyond basic pointer movement, the software provides access to button assignments, sensitivity settings, and profiles for a more personalized setup.

Key Features

• Programmable button controls: Assign shortcuts and macros to the M90’s configurable buttons, making frequently used commands easier to reach during gameplay.
• Adjustable sensitivity: Configure DPI settings to balance precise targeting with faster cursor movement across the screen.
• Game-specific profiles: Create different control layouts for your favorite games or everyday applications instead of changing individual settings each time.
• Device configuration access: Use Corsair’s compatible software to review and adjust supported mouse settings that are not available through standard Windows mouse controls.

How to Install

1. Check your Windows version. Identify whether your PC runs Windows 11, 10, 8, or 7, and check its system type in Windows system information. Choose a download that explicitly lists compatibility with your setup.
2. Confirm the device match. Download the package intended for the Corsair M90 Gaming Mouse. Do not assume software for a newer Corsair mouse supports this legacy model.
3. Connect the mouse. Plug the M90 directly into a USB port on your computer. Close any open mouse-configuration utilities before beginning installation.
4. Run the installer. Extract the downloaded archive if necessary, launch the setup program, and follow the prompts. Approve the Windows administrator permission request if it appears, then restart if instructed.
5. Configure and test. Open the installed utility and verify that it detects the mouse. Adjust button mappings and sensitivity, save your settings, and test them in a familiar application before playing.

Windows may provide basic mouse functionality without Corsair’s configuration software, but advanced customization requires a compatible package. If the utility does not detect the M90, try another USB port and confirm the package’s operating-system requirements, particularly on Windows 10 or Windows 11.

Common Issues and Fixes

• Installer fails or stalls: Disconnect the M90, run the Corsair Gaming Software installer as administrator, temporarily disable antivirus, remove older Corsair software, then reboot before reconnecting the mouse.
• Mouse not detected: Plug the M90 directly into a rear motherboard USB port, not a hub. Check Device Manager for unknown devices, try another USB 2.0 port, and reinstall the Corsair software.
• Version conflicts: Uninstall old Corsair Gaming Software and remove leftover M90 entries, reboot, then install a build that lists the M90. Avoid mixing unsupported iCUE versions, since this legacy mouse may not be recognized.
