License Management

A StarUML license is activated on each device where you use StarUML. You can manage your license in two places:

• License Activation dialog in StarUML (select Help > License Activation menu): activate, deactivate and check the license on the current device.
• License Manager on the web: find your license keys, see the devices where your license is activated, and deactivate them. Log in with your email (the email address entered when purchasing the license).

Check license status

Select Help > License Activation menu to open the License Activation dialog. It shows the following information:

• Status: Activated or Not Activated. (offline) is added if the license was activated offline.
• Product: The product name of the license.
• License Holder: The name of the license holder.
• Device ID: The ID of the current device. Click Copy Device ID to copy it to the clipboard.

Activate license

Activate in the application

1. Select Help > License Activation menu.
2. Enter your license key.
3. Click Activate button.

Activate offline

If there is no internet connection, or external access is restricted due to company security policies, activate your license offline.

1. Log in to the License Manager with your email.
2. Select Devices menu on the top.
3. Select a license. The offline activation guide will then appear in the area at the bottom of the page.
4. Follow the offline activation guide.

Deactivate license

Deactivate your license on a device you no longer use, so that you can activate it on another device.

Deactivate in the application

1. Select Help > License Activation menu.
2. Click Deactivate button.

Deactivate in License Manager

You can also deactivate a device in the License Manager, for example when you can no longer access the device.

1. Log in to the License Manager with your email.
2. Select Devices menu on the top.
3. Click Deactivate button on a particular device, or click Deactivate all devices button to deactivate all devices.

Deactivate offline

If the license was activated offline:

1. Delete activation.key file from the below folder:
   • MacOS : /Users/<user>/Library/Application Support/StarUML
   • Windows : C:\Users\<user>\AppData\Roaming\StarUML
   • Linux : ~/.config/StarUML
2. Deactivate the device in License Manager.

Transfer license to a new device

To move your license to a new device, deactivate it on your old device first, then activate it on the new one.

1. On your old device, deactivate your license.
2. On your new device, activate your license with the same license key.

Once the license is deactivated on the old device, you can activate it on the new device right away.

Tip

If you cannot access your old device anymore, deactivate it in License Manager.

Find a lost license key

Log in to the License Manager with your email to find all your license keys.

License is not activated

When the license cannot be activated, please check the following:

1. Version: Check that the versions of the license and the installed StarUML are the same. You can check the version of the license in the License Manager, and the version of StarUML in About dialog. You can download previous versions of StarUML from the Archive page.
2. Internet connection: Check your internet connection. If there is no internet connection or external access is restricted due to company security policies, try to activate offline.
3. License key: Check that you have entered the license key correctly.
4. Devices: Try to deactivate your license on unused devices.
