WinRar and WinZip offer free trial versions, but you then have to purchase after the trial.
I use 7Zip from http://www.7-zip.org/ . It is free and can unzip both zip files, (WinZip archives), and rar files, (WinRar archives) as well as other compressed file formats.
Try that.

I bought a download instruction manual for my husbands denon receiver and it said I had to have Winrar/Winzip to pen archive and Adobe reader to read the file. I have adobe reader so do I need to purchase the other to archive?
I have windows/7, running IE. 9. Thank you, in advance
