Introduction > Product Registration

To continue using Duplicate File Detective beyond the initial 15-day trial period, you must purchase one or more product licenses.

We offer a variety of licensing options, including single-user, multi-user, site-wide, and enterprise-wide licenses. Please see the "Order" section of our product website for details.

Once you complete the product license purchase process, you will be provided with a license name and key which you can then enter into Duplicate File Detective to "unlock" it for permanent use. When entering your product license name and key, please keep in mind that they must be entered exactly as they were provided to you. The easiest way to ensure correct license entry is to copy and paste these values using the Windows clipboard.

If you have any problems entering your product license details, feel free to contact us at support@duplicate-file-detective.com. We're happy to assist our valued customers.
