I have installed OneNote 2016 via a Japanese university license; I have set everything I can to USA and English (from the first startup installation) with Japanese language packs installed for both keyboard and pen input.

When trying to copy Japanese text from images, which I understand to be using OCR, I get garbage. For example:

Apparently there is a way to change the specified language prior to Right Click > Copy Text from Picture, via Right Click > Make Text From Image Searchable and selecting a given language. Unfortunately, this option appears greyed out, disabled:

I discover that Proofing tools are not installed, and apparently there is no way to install them from within OneNote 2016:

I find a link to download the Japanese proofing tools -- although Microsoft inconveniently puts the webpage and download package in Japanese. They should keep it in English and ask me if I want it in Japanese. I cannot proceed with the installation for two reasons:

My Japanese is not good enough to understand the installation instructions, and I am afraid it will replace the English proofing tools and possibly more. It appears to say it is the 2013 proofing tools, so I do not know if it is compatible with OneNote 2016.

How do I get Japanese OCR working for OneNote 2016?
