Thank you for your answer.
The french package contains only 3 files in the zip archive. But normally, the archive has 2 folders called "admin" and "frontend" in wich there are approx. 70 files. Try to download the german package for exemple and compare it with the french package. All the necessary files are missing in the french package (only the folder "admin" with 2 files in it).
Do you really have a french package with all the 70 files needed? I don't think so.
