LAUNCH Virtual COM Port (COM4) Driver

The LAUNCH Virtual COM Port (COM4) driver lets Windows recognize compatible Launch USB hardware as a virtual serial port, allowing software to communicate with the connected device. You may need it when setting up your equipment for the first time, reinstalling Windows, or troubleshooting a missing COM port or an unrecognized USB connection.

Key Features

• Virtual serial communication: Provides a COM-port interface for compatible Launch equipment connected through USB.
• Software connectivity: Allows applications that use serial communication to access the device through its assigned port.
• Device Manager integration: Makes it possible to check the port assignment and driver status in Windows. Although the device name includes COM4, Windows may assign a different port number.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches your Windows version and system architecture.

How to Install LAUNCH Virtual COM Port (COM4) Driver

1. Check your system and hardware. Confirm your Windows version, whether it is 32-bit or 64-bit, and the model of your Launch device. For Windows 10/11 systems, note that Windows 11 is not included in the listed supported operating systems; verify compatibility before proceeding.
2. Select the appropriate package. Before starting your LAUNCH Virtual COM Port (COM4) driver download for Windows, review the package’s supported devices and installation notes. Choose a trusted source for a free download, and confirm that the latest version supports your equipment.
3. Install the driver. Extract the downloaded archive if necessary, then run the installer and follow its instructions. If the package contains only driver files, open Device Manager, locate the connected device, select Update driver, and browse to the extracted folder.
4. Connect and verify. Connect the Launch hardware as directed by the installation instructions. In Device Manager, check Ports (COM & LPT) for the virtual COM port and confirm that no warning icon appears.
5. Configure your application. Select the assigned COM port in your compatible software. If communication fails, check the USB connection and port selection before attempting another installation.

Keep the driver updated when a compatible release addresses connection problems or supports changes to your system. Before you update a working installation, review compatibility notes and retain the previous installer so you can return to it if needed.
