Oracle Database Discussions

New user here, unable to install unzipped files. In particular a few:

Extracting to "C:\Compiler\Oracle Client\"
Use Path: yes Overlay Files: no
Error in file #1: bad Zip file offset (Error local header signature not found): disk #1 offset: 0
Error in file #2: bad Zip file offset (Error local header signature not found): disk #1 offset: 43

Extracting bin.1.1.jar
Extracting deplib.1.1.jar
Error: invalid compressed data to inflate

Extracting sql.1.1.jar
Error: invalid compressed data to inflate

Extracting oembase.jar
Error: invalid compressed data to inflate

Any ideas? It is possibly a fault of my own. Any advice, for a new learner, would be appreciated.

Kind regards
