I thought changing characteristics from 0x60500020 to 0xe0500020 would help, but no. :/ This change would make the code section writable. FileAlignment you use is probably wrong, I think it should be 0x200 not 0x2000 . Maybe you need to add a data section and fix SizeOfInitializedData too? It just hangs on a blinking cursor, no idea if it actually started executing anything yet or not, since nothing is printed out. ~Maarten
