Flashing Bettaflight 4.0 issue ? SOLVED!

I have a com port #3 I have not downloaded boot loader because I got a com port on hookup.
I hit load firmware online as instructed The flash firmware button lights up shortly after.
I press flash firmware it doesn’t flash a notification pops up at the bottom says loaded online firmware 332260 bytes.
It doesn’t say flashing firmware and show you the loading bar it just gives me loaded online firmware 33226 0 bytes.
Does anyone have any suggestions or know what’s going on? Had to unzip and run zadig and Impulse RC Driver Fixer.
I have an older windows 7 starter computer.
It worked though !!!:crazy_face::face_with_symbols_over_mouth::cold_sweat::cold_sweat::cold_sweat::exploding_head:
So happy I actually got on the floor and prayed during flashing process. Just as I finished praying I heard that awesome beep it was a notification PROGRAMING SUCCESSFUL !!!
