In IDA I see:

mov     ecx, [esp+130h+dwProcessId]
push    eax
push    ecx
call    sub_FE13A0
add     esp, 8
test    al, al
jnz     short loc_FE1261

which is currently returning false which causes the program to terminate. Can someone explain what exactly the conditional in the last two lines are?

    I bet the last two instructions compare the return value from sub_FE13A0(...) with 0 and jmp to loc_FE1261 if it’s not 0 otherwise continue execution past jnz.
