Hi Ferenc,
Good day. You can add another language through an Office 2016 Language Pack or Language Interface Pack, depending on the language you need. Excel 2016 supports languages such as French, German, Spanish, Italian, Japanese, Korean, Chinese, Portuguese, Dutch, and others.
Since you're using the 64-bit version, make sure you download the 64-bit language package that matches your Office installation.
Also, the build number 16.0.4266.1001 is an older Excel 2016 build. Office 2016 reached end of support on October 14, 2025, so some language-pack downloads or installation options may depend on the original Office edition and installation method.
Regards,
Jhun
