# License Information

*Applies to: Patch My PC Publisher*

## Overview

When the Publisher is launched for the first time, you will be prompted to enter a license key.

If you have purchased a license, or if you have requested a free 30-day trial, you will receive an email containing your 20-character license key, which can be entered into the **License Key** field on the **General** tab in the Publisher, to activate the appropriate functionality.

If you do not currently have a license key, you have 2 options:

* Enable Limited Trial Mode, which allows you to evaluate Publisher with a restricted set of products.
* [Request a free 30-day trial](https://patchmypc.com/free-trial) from our website to have your license key emailed to you.

Once a valid license or trial key is entered, Publisher will unlock the corresponding features and allow you to proceed with configuration, customization and publishing.

If validation fails, the dialog indicates that the key could not be verified and typically suggests checking either the license value or [network connectivity](https://docs.patchmypc.com/publisher-requirements/core-requirements#network).

## Limited Trial Mode

If you do not yet have a license or trial key, the Publisher can be used in Limited Trial Mode. This allows you to evaluate Publisher functionality using a predefined set of products.

### How to enable Limited Trial Mode

2. Navigate to **General > License Information**.

## Subscription Information

This section displays details about your current Patch My PC license, including the subscription tier, license validity period, and the number of devices covered. This information helps confirm that Publisher is correctly licensed for your environment and that your device count aligns with your deployment scope.

* **Subscription level**\
  Indicates the Patch My PC license tier currently applied (for example, *Enterprise Premium*). The subscription level determines the features, products, and capabilities available within Publisher. The [available subscription](https://patchmypc.com/pricing/) levels are:
  * Enterprise Premium
  * Enterprise Plus
  * Enterprise (Enterprise Patch)
* **Expiration date**\
  Shows the date on which the current license or trial expires. Publisher will continue to function normally until this date. Once the license expires, new applications and updates will no longer be published. Any applications and updates that were published prior to the expiration will remain available and unaffected. To avoid interruptions, renewal or trial extension should be planned ahead of the expiration date.
* **Licensed device count**\
  Displays the maximum number of devices covered by the license. This should align with the number of managed devices that will *receive* applications or updates published by Publisher, which may differ from the total number of managed devices in your environment.
