1. Save the node license file (something.lic) you received from us in a permanent location that you can find easily.
2. Run Windows Start->Isologica General->License Locator (Or Windows search for "License Locator")
3. Click on "Add License File"
4. Browse to the license file saved in Step 1
5. Click OK and then Close
6. Optional: If you already had a license server configured, you will see additional lines in the screen as per the screenshot below. This is OK - you will still use the license file just added if you select the license file line and click the Up button.
7. License configuration is complete. Restart Isologica and this new license file will be used.
