How to Install Thorlabs DC4104 (COM15) Driver

1. Confirm your system details. Check your Windows version and system architecture before choosing a package. For Windows 10/11 systems, note that Windows 11 is not included in the supplied compatibility list; verify support before proceeding.
2. Choose a compatible download. When selecting a Thorlabs DC4104 (COM15) driver download for Windows, confirm that the package explicitly supports your hardware and operating system. Look for the latest version compatible with your setup, rather than assuming the newest release supports older Windows editions.
3. Prepare the files. Obtain the package from a trusted source, whether offered as a free download or bundled with device software. Extract compressed files and review any included installation instructions.
4. Install the driver. Follow the supplied installer instructions, including any guidance about when to connect the USB cable. If the package contains only driver files, use Device Manager’s driver-update option and browse to the extracted folder.
5. Verify the connection. Restart Windows if prompted, then check Device Manager for warning icons. Confirm the assigned COM port and select that same port in your compatible control application.

Keep the driver updated when a compatible update addresses a problem or supports changes to your software environment. Before replacing a working installation, review the release notes and retain the previous installer so you can restore your setup if necessary.
