How do I remove the license warning or expiration pop-up in Dynamsoft Barcode Reader?

When using Dynamsoft Barcode Reader SDK without a valid license or with a temporary license, a warning pop-up appears at startup to notify you of the licensing status.

Temporary License Warning

With a temporary license, the SDK provides 24 hours of usage for testing purposes and displays the following warning:

Expired License Warning

After the 24-hour period expires, the warning changes to indicate the license has expired, and scanning functionality is disabled:

Solution

To remove these warnings and restore full functionality, initialize the SDK with either:

• A purchased license, or
• A 30-day trial license

Once a valid license is applied, the temporary license warnings will no longer appear. You can refer here to apply for a 30 day trial license.
