Just look for strings

and after u found one check upper should be something JE or JNZ
change it to JMP and u`re done
normaly its would be look like
Code:
if SumOf(Enc) = AllCool then
..
..
some code
..
..
else
begin
ShowMessage('Enc file corupt bla bla');
end;
so u only need skip this part
Code:
else
begin
ShowMessage('Enc file corupt bla bla');
end;
should be very easy just take your time

and be patient nothing hard there
