The "Could Not Start Driver" error in FTK Imager typically occurs during memory capture attempts or application startup, often due to permission issues, missing dependencies, or hardware incompatibilities.

Below are proven methods to fix this error, ranging from simplest to most advanced. Perform them in order unless a shortcut applies to your environment.

This error typically appears the moment you try to launch the application. You double-click the icon, wait for the splash screen, and instead of the GUI, you are met with a cryptic message box: "Could not start driver new." The application then shuts down.

If you are using (version 3.1.1 or older), you may face constant driver issues on modern Windows builds due to revoked signing certificates.

If the error persists, a previous FTK Imager instance may have left a locked driver.
