There is currently no option to change the language settings of a particular install of LabChart for Windows. The three supported languages, English, Chinese, and Japanese, exist as independent versions of the software. To change from one language version to another, you will need to overwrite the current installed version with the desired language version. The installer for a particular language version can be downloaded from this ADInstruments' webpage.
Note: the LabChart for Mac software is only offered in English at this time.
