The Canon PowerShot SD790 IS driver helps Windows recognize your camera when you connect it by USB, allowing compatible software to access photos stored on the camera. Before downloading, check that the Canon package supports your Windows version; some systems may handle photo transfers through built-in Windows support rather than a separate camera driver.

Key Features

• USB camera recognition: Helps establish communication between the Canon PowerShot SD790 IS and your computer when the correct driver or Windows device support is available.
• Photo transfer support: Enables compatible import tools to retrieve images from the camera for viewing, organizing, and backing up.
• Integration with compatible software: Provides the device connection needed by supported photo-management applications. Editing and organizing features depend on the application, not the driver itself.
• Windows compatibility checks: For Windows 11, 10, 8, or 7, verify the download’s listed requirements and whether it matches your system’s 32-bit or 64-bit architecture. Older Canon software may not support every version.

How to Install

1. Check your Windows version. Open your system information and confirm the operating system and system type. Review the download details to ensure the package explicitly supports both your camera and your version of Windows.

1. Prepare the camera and connection. Charge the camera battery and have a compatible USB data cable ready. Leave the camera disconnected during installation unless the package instructions say otherwise.

1. Install the supported package. If a separate driver is provided for your system, download it from a trusted source, extract the files if necessary, and run the installer. Follow the prompts and restart Windows if requested. Do not force an unsupported driver to install.

1. Connect the Canon PowerShot SD790 IS. Attach it directly to a USB port on the computer, turn it on, and select playback mode as directed by the camera manual. Allow Windows to detect the device and complete any automatic setup.

1. Test a photo import. Open a compatible Windows photo-import tool or supported Canon application and try transferring a few pictures. If the camera is not detected, check Device Manager, try another USB port or data cable, and consult the camera’s connection instructions. A compatible memory-card reader is an alternative if direct USB transfer is unavailable.

Common Issues and Fixes

• Installer fails or stalls: Disconnect the PowerShot SD790 IS, run the Canon installer as administrator, and remove older Canon camera software first. On Windows 10/11, prefer the built-in USB/WIA support instead of legacy Solution Disk drivers; use compatibility mode only if you must run the old installer.
• Camera not detected: Use a data-capable USB cable directly into a rear PC port, not a hub. Power on the SD790 IS in Playback mode, check Device Manager for unknown devices, and try another cable/port. If Windows still misses it, remove the SD card and use a card reader.
• Version conflicts: Uninstall old Canon WIA/TWAIN drivers and camera utilities, reboot, then let Windows install its native driver. Don’t mix legacy Canon software with newer Windows; if an app can’t see the camera, select the correct WIA import option.
