Mon espace virtuel. Mansoura

Hi,

I am using Joomla! 2.5.14 . I have been trying to install a French language pack unsuccessfully (fr-FR_joomla_lang_full_2.5.1v1 ). I have download the files but when I try to upload it onto Joomla! 2.5 under extension manager, this comes up " 
JFolder::create: Could not create directory Path: /home/content/73/12039173/html
Warning: Failed to move file!
"
The file ( fr-FR_joomla_lang_full_2.5.1v1 ) is currently placed under downloads on my computer files. I have tried to move the file to the desk top to change up the directory path but this has also been unsuccessful, any ideas?

Any help will be apprecited.

I didn't find the right solution from the Internet.
