Checksum Error Install Maxify MB5420 Drivers Win 11

[MyHome]

I have a new computer and am trying to install the drivers for the 5420.  I am running Windows 11, and was successful with the driver that is a part of Windows, but need to install the scanner drivers.  I have downloaded the latest software to do the installation (win-mb5400-1_1-n_jucd Canon Drivers Full).  The constant error is the "CHECKSUM is not a valid Win32 application".  I tried installing both as an administrator and regular user.  Are there any recommendations you have for me?  Thanks.

Sounds like the download might be corrupted try re-downloading the installer directly from Canon’s official site, maybe with a different browser. Also make sure you’re grabbing the Windows 11-compatible version.

Thank you so much for this reply.  I downloaded 2 installation programs from the US and Canada sites and they failed.  I wonder if there are some dependent files somewhere on the computer that are corrupt.  Do you know if there is some other way to do the install?  Is there a way to manually put the drivers in to the proper spot, or, clean out all of the dependent files - if they exist?  Thanks.

Yeah, I had a similar issue before. What worked for me was using a cleanup tool like Revo Uninstaller to fully remove any leftover files, then doing a clean reinstall. You can also try manually installing the driver through Device Manager if the setup keeps failing. Worth a shot!
