License Expiry Message? We’ve Got you Covered!

You are getting the message “Your License is about to expire … “ or “ Your license of Visual MODFLOW has expired”.

Don’t panic – we’ve got you covered.  When using Waterloo Hydrogeologic applications that were released prior to 2014, you may encounter the message “Your license is about to expire on: DD-MM-YYYY…”

This message will appear in advance of the day of license expiration – don’t be alarmed.  You can still continue working in the application without any disruption until the expiration date.  The license technology used in our applications prior to 2014 required a license expiration date.  This simply means we need to reactivate your license; which can be done quickly.

To address this issue, you will need to contact the support team.

  • Take a screenshot of the message
  • Retrieve the serial number of the application from a Purchase Order or from the Main menu ( > Help>About page)
  • Email these details as indicated in the warning message.

Why does this happen if I have up to date maintenance?

As mentioned, prior to 2014, our applications required a license file that had an expiration date.  If you have valid maintenance and experience this message, it means you are not using the most current version of the application.  Releases after 2014 have perpetual licenses that do not expire – they remain active forever.  As an added bonus, they can also be activated (licensed) automatically without any involvement from the technical support team as long as you are connected to the internet.  New features, bug fixes, unlimited access to technical support and more streamlined licensing…lots of great reasons to keep your software and maintenance up to date!  Contact us for more details.
