If the installed version continues to fail, many forensic investigators switch to FTK Imager Lite. Since the Lite version is portable, it doesn't always go through the same rigorous installation process for drivers, which can sometimes bypass registry-related permission errors. Ensure you run the "FTK Imager.exe" from the portable folder as an administrator. Summary Checklist Administrator Rights: Is the program elevated?
