Bonjour et Bienvenue sur le forum:
Can you please explain, in English (it's a US based site) what the precise issue is?
So far, it looks like you are trying to update the firmware on your Canon EOS T7 (which is a North American model name, in Europe it would be the EOS 2000D). It appears you are working with English as the message is in that language.
To download the correct firmware you need to go to the EOS 2000D (or T7) Canon support page. The process will then be slightly different for Macintosh vs. Windows. Usually the site senses which operating system you are using, but if not you will have to manually select it.
In both cases, you then need to upload a compressed image file to a hard drive on your computer and then expand that compressed file to generate a file with a .FIR extension. It is that file which you copy onto an SD card and insert into your camera.
When you go to the wrench menu to do the upload, which you seem to have done, the camera will then read the .FIR file and proceed. NOTE: make sure your camera battery is fully charged before starting the process with the camera.
cheers, TREVOR
