If you have the FR language files (from another installation?) here:

<path>/resources/fr/

you can try a language switch like this

<path>/Sketchup.exe -lang fr

Have you tried a simple uninstall of the original and an install of the french version?

No, I don’t have the french langage file

Box, thank for your answer.
I don’t know how to uninstall the software can you telle me what to do?
Besides I am afraid that when I’ll download the French version, the serial number will not be accepted cause already used. what do you think?
