Upgrade to Version 4

Single user upgrades completed

If you are entitled to a free upgrade to v4 (see below) you may now use your existing v3 activation code in DesignBuilder v4.

If you have problems with your v4 activation code urgently please submit a support ticket stating your activation code.

Site license upgrades completed

All eligible site licenses have been upgraded to v4. You will need to follow the site license activation procedure to obtain your updated .lic file for use with your existing license server. This new .lic file replaces your existing .lic file for use with the license server. The new .lic file will allow DesignBuilder v3 and v4 to run so you do not have to immediately upgrade all the installations of DesignBuilder on your network.

Are you entitled to a free upgrade to v4?

If you have a current annual subscription license are eligible for a free upgrade to v4. 

Also, if you purchased a v3 license on or after 1 November 2013 you are eligible for a free upgrade to the equivalent v4 package.

To obtain the free upgrade:

  • Download and install the latest version 4 software from our website
  • Run DesignBuilder
  • Open the License dialog using the "Help > License" menu option
  • Click the License button and use your existing activation code

You will now have access to the equivalent v4 package you purchased in v3, e.g. if you purchased a Design Simulation v3 package, you will have access to the Engineering Essentials v4 package, which as well as EnergyPlus, Visualisation, HVAC and Daylighting modules includes the new Cost module.

Or a 40% upgrade discount voucher?

Customers who purchased a v3 license before 1 November 2013 are eligible for a 40% discount to upgrade to any v4 software.

If you purchased directly from DesignBuilder UK then please contact us to obtain your discount voucher code. Quote your activation code or invoice number to allow us to send you a discount voucher code directly.

If you purchased through one of our international resellers then please contact them to obtain your discounted upgrade to v4.
