# License Upgrade Eligibility

When a Vehicle Spy license is purchased it includes one year of free software updates. Additional years of software updates can be purchased at the [Intrepid Control Systems store](https://store.intrepidcs.com/).

License expiry behavior differs depending on the license type in use. See the sections below for details.

### File License Expiration

License upgrade eligibility for hardware-based licenses is found on the **License** tab at Tools → [Options](/vspy-3-documentation/vehicle-spy-main-menus/main-menu-tools/tools-options.md) in the Vehicle Spy main menu.

Select a license file from the **License Files** dropdown. The **License Information** group will populate with the details stored in that file, including the **Upgrade Eligibility** date. This date indicates how recent a version of Vehicle Spy that license file will allow to run.

* If the **Upgrade Eligibility** date is **later than** the release date of the Vehicle Spy version you want to install, you can upgrade without issue.
* If the **Upgrade Eligibility** date is **earlier than** the release date, that license file will not allow the newer version to run. The currently installed version will continue to work normally.

If you have more than one license file (for different hardware units), verify that all hardware units you intend to use are covered by a license file with a sufficient **Upgrade Eligibility** date. The serial numbers authorized by a given license file are listed in the **Licensed Hardware** box in the **License Information** group.

To remove old or unneeded license files, click **View License Folder** to open the license folder in Windows Explorer. From there you can delete outdated files or add new ones.

Please [contact](https://intrepidcs.com/contact-us/) Intrepid Control Systems for information on purchasing additional upgrade eligibility time.

### PC-Locked License Expiration

A `PC-Locked` license grants full use of Vehicle Spy for a fixed time period from the date of activation. Unlike a hardware-based license, there is no "Upgrade Eligibility" concept — the license simply allows Vehicle Spy to run until the demo period ends.

When the demo period expires, Vehicle Spy will no longer launch until a valid license is applied. To continue using Vehicle Spy after a demo expires, either activate a new demo license or contact [Intrepid Control Systems](https://intrepidcs.com/contact-us/) to purchase a full hardware-based license.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.intrepidcs.com/vspy-3-documentation/vehicle-spy-main-menus/main-menu-tools/tools-options/options-license-system/license-upgrade-eligibility.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
