Warning that barcode type is locked

Registration file not installed correctly


When WBC4 launches it looks for a registration file inside the folder WBC4 Registration File in the WBC4 Documents folder which is contained on your Documents folder.

This file contains the serial number which confirms your licence to use the software.

If the file is not found, WBC4 launches as a demo copy (you can't save barcodes).

When you purchased WBC4, you would have been sent a registration file, either on CD or by email.


1. Locate the registration file that was sent to you (as a file on the CD or as an email attachment).

2. Launch WBC4 and choose the Unlock/Upgrade option from the Help menu.

3. Click the Locate button and open your registration file. WBC4 will move the file into the correct location.

4. You should now be able to save barcode files.
