If you need a commercial license, here’s what to do:

  1. Determine the MAC address of the PC you want to run Glade on. You can either run the ‘hostid’ executable shipped with the distribution, or check the logfile which will have a line like ‘MAC address: 2C:6D:C1:8F:C7:E5’. The 6 pairs of hex numbers are the MAC address.
  2. Send this to
  3. Pay £100 via PayPal to
  4. You will be sent a license file within 24 hours. Then, just save the license file on your machine and set the environment variable ‘GLADE_LICENSE_FILE’ to the absolute file path of the license file (including the file name itself).

Also for commercial users we offer a support contract offering priority response to technical queries and usage, with tracking of issues and dedicated sftp login for data transfer. Please use the contact page to ask for more details.

Installing licenses

To install a license, save the license file to some location. For example C:\Users\MyName\license.dat on Windows or /home/MyName/license.dat on Linux.

Next, set an environment variable to point to this license file. On Windows you can do this by opening Search and entering “Edit system environment variables”. Then, in the System Properties dialog, click on ‘Environment Variables’. In the User Variables section, click on ‘New’ and add the variable name as GLADE_LICENSE_FILE and the value as the license file location e.g. the above C:\Users\MyName\license.dat. Click OK to save the environment variable.

On Linux you can edit your .bashrc and add a line to specify the environment variable name and value:

export GLADE_LICENSE_FILE=/home/MyName/license.dat

Don’t forget to open a new shell (or source your .bashrc) for this to take effect.

When you next start Glade, you should see in the logfile something like:

  • # Reading license file: /home/MyName/license.dat
  • # – Enterprise feature enabled.
  • # – Advanced DRC feature enabled.

If not, check the environment variable name and value is correct.
