Resolved Please recommend a free version of a RAR extractor utility

If I plan to use it under Win7 Ultimate 64 bit, is it absolutely necessary to download and use a 64 bit version, or will any version do just as well. I have several computers in my home, and only one is 64 bit.

 

Hi Broni,
Thanks so much for your reply. That is exactly the last page that I looked at before I decided to post my question here.
I see that there is a 64 and a 32 bit version of this program.
Thaks again.
I'll mark this thread as resolved.
