| 11 | + |

| 13 | + |
| 14 | +## Does the license key expire? |
| 15 | + |
| 16 | +Yes, the license key expires at the end of your support subscription: |
| 17 | + |
| 18 | +* For trial users, this is at the end of your 30-day trial. |
| 19 | +* For commercial license holders, this is when your subscription term expires. |

| 70 | +See the [Invalid License]({%slug license-errors-and-warnings%}#invalid-license) section for more information. |
| 71 | + |
| 72 | +Note that future updates of Telerik Report Server may restrict or disable some features when no valid license is present. |
| 73 | + |
| 74 | +## I updated the Telerik Report Server and the invalid license errors have appeared. What is the cause of this behavior? |
| 75 | + |
| 76 | +If this happens, the possible reason is that the end date of the license activated in your application is before the release date of the newly installed product. To fix this issue: |
| 77 | + |
| 78 | +1. [Download a new license key]({%slug license-key%}#downloading-the-license-key). |
| 79 | +1. [Activate the new license key]({%slug license-key%}#activating-telerik-report-server) in your project. |
| 80 | + |
| 81 | +## Do I need an Internet connection to activate the license? |
| 82 | + |
| 83 | +No, the license activation and validation are performed entirely offline. |
| 84 | + |
| 85 | +The license is not validated with our services at any point in the project lifecycle. |
| 86 | + |
| 87 | +## What happens if both the environment variable and the license key file are present? |
| 88 | + |
| 89 | +If both the `TELERIK_LICENSE` environment variable and the `telerik-license.txt` file are present, then the environment variable will be used. |
| 90 | + |
| 91 | +To enforce the use of the license key file, unset the environment variable. |
| 92 | + |
| 93 | +## Are earlier versions of Telerik Report Server affected? |
| 94 | + |
| 95 | +No, versions released before __January 2025__ do not require a license key. |
