rtcw wont install =[

i decided to dig out rtcw goty edition for a laugh. I insert disc 1 and part install, then it asks for disc 2, so i put it in and it installs a bit more, then it asks for disc 1, so i put disc 1 in and nothing happens, the cursor goes to egg timer and the program doesnt respond. If i eject the disc then it asks me to put disc 1 in again.

help plz :<
