Not a valid Win 32 Application?

I copied a few game cds with CCD and when i went to run the setups from the disk to test them out it came up with the message “E:\ETC.exe is not a valid win 32 application”. It does it with every CD and every single file. My CD Writer is a Toshiba SD-R1002 DVD/CD R/RW Combo. My system recognizes the cd and the games run fine with it , recognising it as the origonal cd, but in general they are totally useless.
