assembly – Masm not assembling my win32 program in visual studio


Guys I been trying to asssemble my masm32 file in visual studio but the build fails each time. there isn’t an issue with my program as it runs on other machines perfectly well it’s only i think a problem with dependecies or sth or me not runnning this asemmbly file on some older windows version I guess but i tried everything peraps you could point me out to what the problem is

here is the output I get when I try to build it
