I have successfully installed the red alert 1 which i downloaded the disk files from internet (allied disk and soviet disk) when i run the RUNGAME.EXE, it says "PLEASE INSERT A RED ALERT CD INTO THE CD ROM DRIVE" FYI, i have burned a cd named CD1_ALLIED_DISC but still it require disk... anyone can help? Thanks in advance

It ask for CD, for your information, i dont have CDs and i install it from the files i download from Internet... I've successfully install the game but just cant run without the CD. any solution for this?
