[Help] App always crash and error "the exe is not valid win32 app"

[Arizoenna]

Recently i tried to install dual boot android then it's failed and it forced me to recover windows bootloader,
then it's started getting error like the tittle, i've tried re-installing windows as my os is 64 bit.
and it's still getting error especially on steam games, i can't play and keep verify integrity and loop..
Sorry for my bad english.
