Hide CD-R Media and C and C Renegade prob.
 

Where is the option to hide the CD-R Media in CloneCD? I can't find it.

I have made a back up of C and C Renegade. I can install the game completely, but after the installation the game won't start.
I have heard a crack would solve this problem. But is there a way, where I don't have to use a crack. I thought CloneCD can make 1:1 copies? I don't have activate "Hide CD-R Media", cuz I hadn't find the option. If I would activate this when burning again, can I play the back up without a crack or is the crack a must have for playing the game?

Right click the CloneCD icon in your system tray. Hide CDR Media is there. Just select it.
