I notice there's an update for Firefox with latest version is 6.0.2, when I applied the update and the download process runs perfectly but when at the installation process..

As I know at this process all done without any re-downloading any of it... but for the update of this Firefox 6.0.2, LiberKey ask me to download again the update files and always re-downloading when it's done and rolling again...

I also have the same issue, use the .lks instead (offline setup)

thanks mate.. it works... better the LiberKey team fix this one.. or make the full offline installation with multi-language..

offline setup is already multi langauge, check third tab
