License Limitations

: Most commercial licenses are "localized," meaning a license for one region (e.g., German) may not support running a different language version (e.g., French). However, many users report that an INT (International) license can often run other English-based versions like USA or AUS.

In Archicad 26, you cannot change the user interface language through internal settings or preferences because the language is deeply embedded in the program's structural code

Check License Compatibility

: Your license must support the language version you intend to use. For example, local licenses (like a UK-specific license) may not work with the International (INT) version unless you have a global license or specific permissions according to Graphisoft Support .
