• Windows support: Listed supported systems include Windows 10, Windows 8.1, Windows 7, Windows Vista, and Windows XP; confirm that the selected package matches your system.

How to Install Altium Spi/Unio over USB Driver

1. Check your Windows version and system type. Determine whether your installation is 32-bit or 64-bit before choosing a package. If you are checking Windows 10/11 compatibility, note that Windows 11 is not included in the listed supported systems.
2. Select a compatible package. Before starting your Altium Spi/Unio over USB driver download for Windows, review the available compatibility information. Choose the latest version that explicitly supports your operating system and hardware.
3. Download and extract the files. Use a trusted source for a free download, and check that the package identifies Altium and the correct device. Extract the archive if necessary.
4. Install the driver. Follow the included setup instructions, using administrator permissions if requested. If the package has no installer, open Device Manager, locate the device, choose the driver update option, and browse to the extracted driver folder.
5. Verify the connection. Restart Windows if prompted, then reconnect the interface. Check Device Manager for warning icons and confirm that your compatible Altium software can detect the hardware.

Keep the driver updated when a compatible release addresses a problem or supports a change to your system. Before you update, review any release notes and retain a copy of the working driver package. The latest version is useful only when it matches your device and Windows installation.
