**PDF.js Express Version**

**Detailed description of issue**  
I am getting the pdftron watermark even after adding license key to the Webviewer. Is there any way to remove that? Watermarks are coming in both development mode and production mode.

async ngAfterViewInit(): Promise {  
WebViewer({  
licenseKey: ’ ', //added my license key here  
disableFlattenedAnnotations: true,  
path: ‘…/…/…/…/…/wv-resources/lib’,  
config: ‘…/…/…/…/…/wv-resources/lib/ui/config/file.js’, // relative to your HTML file

Hey there!

You should not be getting a PDFTron watermark at all - are you using the right library?

If you have ever switched from Express to PDFTron, make sure all the old files were deleted before switching.

Thanks!
