I do not know where the problem was but I took everything back to 0 (downloading files ...) by applying> cd flash and it works ... Thank you very much @Alex Rogers ... I think it may be from the flash version chosen by trying to try I had to select the windows32 version of flash

I managed to make > cd flash but I get that ...
