Another common problem on Windows 10 is a permission error that prevents the scanner from being detected. In this scenario, the utility may launch but report that no scanner is available.

From there, they adjusted the security permissions to grant "Everyone" full control over the executable.
If you cannot find a working old version of the Canon utility, you have one final option. Windows Image Acquisition (WIA) is a built-in protocol that ignores Canon’s proprietary software. While you lose some features (like single-click multi-page PDF), you gain raw stability.

There are two primary scenarios where older software is needed:
Canon does not officially support downgrading the MF Scan Utility for modern OSes. If you install an old version on Windows 10/11 or macOS 12+, you may get crashes or missing scanner detection.
Instead of searching for the utility alone, go to the Canon Support Site and enter an older printer model (like the MF230 or MF240 series). These often link to slightly older, more stable versions of the software in the "Software" or "Drivers & Downloads" section.
Canon periodically deprecates older imageCLASS models in its software updates. An older utility version ensures your legacy printer-scanner remains fully operational.
A major compatibility issue arose following Microsoft's 24H2 update. Users reported that after updating their systems, the MF Scan Utility failed to scan, displaying an error message that the scanner could not be found or that the cable was disconnected. This issue was widespread and affected multiple versions of the utility on both Windows 11 and Windows 10.
