That error code means the key container couldn't be found or accessed, but that doesn't make sense because the patcher is providing the key. Either there's an issue accessing the folder under %APPDATA%\Microsoft\Crypto\RSA, or something else is screwed up. Try deleting that folder, and if that doesn't work, try creating a new administrator user and running the patcher from that account.

You can also try the older version, which requires test mode: https://www.monitortests.com/atikmdag-patcher-1.1.2.zip

If the older version doesn't work either, then something is screwed up on your system. Nobody else has ever reported that particular error code.
