I didn't make it!
can anyone tell me how raly to instal that COD main g.to run it without any problems?
Yes you do
Not sure what your saying dude, but if it's 'can I run COD without the file defaul.cfg?' the answer is you can't, coz there isn't 1 file there are 3 (located in pak0.pk3. pak2.pk3, and pak5.pk3).
