Hi there,

It looks like you have a license key already generated from your account settings on pdf.js.  
You can regenerate them in the same panel:

Hi there,

It looks like you already have a license key for that domain. In that case, you would need to edit your first license key to something else then create a new one for that domain.

I have generated a new license key and placed it on our website www.groupemutuel.ch but the watermark is still there. Do you have a way to check if the new key is used by www.groupemutuel.ch?

Hi there,

I took at look at the staging link you provided and it looks like you have the annotation tools in the header. This means you are not using the pdfjs express viewer. Make sure you have the correct package installed.

You can see the difference in the packages here:

> **[PDF.js License Pricing for Commercial Viewer | PDF.js Express](https://pdfjs.express/pricing)**

and the demo between viewer/pro: [PDF.js Viewer Demo | PDF.js Express](https://pdfjs.express/demo?product=viewer)

Have you tested this link (our site in PRODUCTION) [Search engine: results - Groupe Mutuel](https://www.groupemutuel.ch/en/private-customers/search-results.html), by clicking on the View button to open the viewer?

Hi there,

Yes I looked at your staging and see that you have the express Plus features:

You will need to correctly download the pdfjs-express-viewer package
