Although there is no charge to download the evaluation version of WinZip, WinZip is not free software. The evaluation version gives you the opportunity to try WinZip before you buy it. Anyone may download the evaluation version of WinZip from the WinZip web site.
If you would like to continue to use WinZip beyond the evaluation period, you will need to purchase a WinZip license. You may do so by selecting one of the Buy Now links on the WinZip home page.
If, after the evaluation period, you decide not to purchase a WinZip license, then at that point you should remove WinZip from your computer. Please see How to uninstall WinZip for the correct steps.
Feel free to submit a ticket to WinZip Service using this form if you have any additional questions.
