where to install Recuva?

I am trying to recover accidentally deleted files from my C drive. I do not want to write on my C drive or install any software fearing that it might overwrite the deleted files. So I was wondering if I install recuva on my C drive, it could overwrite the files I am trying to recover.

How do I go about this? Is there an option to make a CD or flash drive out of it and run recuva from them?

thanks
