Bootstrap Studio is a powerful desktop app for creating responsive websites using the Bootstrap framework. It has a drag and drop interface, built-in components, code editing, live preview, and more. But how do you activate Bootstrap Studio with a license key? Here are the steps you need to follow:

1. Download Bootstrap Studio from https://bootstrapstudio.io/. You can choose the version for Windows, Mac, or Linux.
2. Open Bootstrap Studio and enter your license key. You should have received an email with your license key when you purchased Bootstrap Studio. If you lost it, you can recover it at any time from https://bootstrapstudio.io/recover-license.
3. Give your computer a distinct name. This will be shown in the Manage Devices dialog later, where you can see and remove all the computers that are activated with your key.

Note that your license key can be used to activate three copies of Bootstrap Studio at the same time. If you want to deactivate a copy, you can do so from the Help > Delete License Key menu. You also need to have an active internet connection so that your key can be validated.
