Hi, I’ve just downloaded and installed the vision web browser component and it doesn’t seems to work. If I add the component on my view, I have the following error message when trying to open the view: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/6/606115d04cb2f6c399426694116f8f95425017ca.png) If I delete the component my view can open again. Any idea?? Thanks, ---

Can you click that “full” button and put the details here too? What version of the module did you download? ---

It’s version 4.0.12.

If you go to Help -\> About Ignition Designer (from inside the designer) can you confirm the web browser module is showing up with a valid state? Or check the designer logs on a fresh startup - see if there’s an error about not being able to load the module for some reason. ---

Ah, he said this got fixed by upgrading to Ignition 8.0.12 to match the module version, but that info got moved away into the new topic.
