Request a license

You are very welcome to apply for a free license string to test any of the Huygens Software functionalities!

The software has plenty of useful freeware utilities that work directly, without any further license. Still, if you want to go beyond this and try all its powerful restoration and analysis tools you will need a license key. This temporary license key can be obtained for free by requesting a license online (following the instructions after installing and running the program, recommended) or by sending us a reply on the email that was sent to you when you downloaded the software.

In the latter case, please answer the questions in the email and paste your computer's system ID at the correct place. Your computer's system ID can be read in the Menu item 'Help -> About' in the Huygens Essential and 'Help -> Product Information' the Huygens Professional.

Once we have received the system ID together with the information from your reply and the original email, we will generate a personalized license for your system. This license will only work on that specific computer.

When we send you the license string you will also get its installation instructions.
