For some reason when going to play Call of Duty 2, i all the sudden get a message that MSVCR80.dll is missing and it tell me to install it. I go to the I-net and download that .dll and tried installing it in various places mentioned here and there and still I get the same message and COD2 will not play. I have the dll file but where and how shall I install so this message does not come up? i unistalled the program and anything else I can find and nothing same message. Should I do an OS repair?
