Activate Pro (Redeem License Key)
Activation means removing the daily usage time limit with a license key after purchase. Once activated, the current device can dim without a time limit.

How to Activate
- After purchasing, you will receive a license key.
- Open VeilWin → Settings → License.
- Enter the license key and click Verify / Activate.
- Once activated, the UI shows “Activated” with the license info, and the daily time limit is removed.
The activation state is written to local config and refreshes the front-end License Store, so Pro remains active while offline as long as the license has not expired.
Device Slots & Management
VeilWin uses per-device licensing: one $8.59 lifetime license covers up to 5 devices. On the Settings → License page you can see:
- Machine ID: the unique identifier of the current device
- Device slots:
{used} / {max}devices used - Bound device list: device names and unbind actions
When the device limit is reached, activating on a new device shows “Device limit reached”. You must unbind an old device first.
Unbind Devices
Unbind This Device
In Settings → License, click Unbind this device and confirm. This will:
- Remove the current device from the license’s bound device list
- Revert the local Pro state to Free
- Free up one device slot
Unbind operations are rate-limited by the server. If you see “Unbinding too frequent”, please try again later.
Unbind Another Device
In the bound device list, click the delete button next to another device to remotely unbind it. This does not affect the Pro status of the current device.
Restore Purchase
Cross-Device Recovery (CDKey)
Enter the same license key on the new device to restore Pro. If the device limit is reached, unbind an old device first on any previously bound machine.
Common Errors & Solutions
| Message | Cause | Solution |
|---|---|---|
| License key not found | The CDKey does not exist in the system | Check that the key is entered completely, including hyphens, and watch for case sensitivity |

Notes
- A license key is bound to the current device once verified. Do not share it with others.
- When switching devices, unbind the old device first, then activate on the new one.
