I am trying to get the latest version of the Client Tools and when I use 7-zip to unzip the 7.33.0.zip file, they all unzip to 0KB files that are completely empty. What am I doing wrong? Thanks.

Try again, it works fine on my machine.
I've tried it twice. Maybe I'll see if I can download the zip from the original email again.
Ah, sorry. I thought you meant the free version.
I don't think I even knew there was a free version. Now I'm dead in the water. I can't get anything to run even putting the old stuff back in. Rick's apps make me feel so inept. hahahaha.

Is the file download 0 bytes or is there a problem unpacking the zip file?
Default Windows decryption doesn't work because the file is encrypted with higher level of encryption - you can use 7Zip or most other Zip utilities.
If the file is 0 bytes I suspect your anti-virus might be interfering - there are binary files in the archive and PRG files which at some point were executable.
