Impossible to write on the SD card

Good evening, I got a problem with installation Support Package for Raspberry Pi process. Matlab couldn't find my SD Card even if windows did. So, I runned Matlab as administrator and wrote targetupdater in command. Then, Matlab detected my SD card. But, it isn't possible to write on it, I got this error : "Error writing firmware to the memory card: An error occurred while locking the SD card volume. An error occurred while unlocking the SD card volume". Meanwhile, my SD card is unlocked, so I don't understand.
