Itunes and quicktime player problems

So itunes always asked me if i wanted to upgrade to the higher version and i always said no. I finally said yes and then it wanted me to download a higher version of quicktime player. But the problem is I can not download it because I have an older mac. Is there anything i can do to get back into my itunes? maybe is there a way that i can recover my mac to before i downloaded the new itunes. your help would be greatly appreciated thank you!!!!!!!
