Hi Philippe Riondel 

The plugin is there as you can see here:

Please configure the integrated AppStore of your Studio 2022 as explained in the document mentioned in the yellow warning on top of this website and you will see the plugin and be able to install it directly by clicking on the down arrow or the green 'Install' button. 
Do not use the SDL Plugin installer for this.

Fantastic! It worked. But it is not that intuitive, IMHO.
Thank you Walter

I did all of the above and Web Lookup is listed as installed but I don't see it in the Editor nor in the list of shortcuts after restarting. Anyone else having problems with Web Lookup... it's indispensable.

I think your best bet is to close Trados Studio, delete these folders, restart Trados Studio and then reinstall your apps using the integrated appstore:

 c:\Users\[USERNAME]\AppData\Roaming\SDL\SDL Trados Studio\16\Plugins

c:\Users\[USERNAME]\AppData\Local\SDL\SDL Trados Studio\16\Plugins

c:\ProgramData\SDL\SDL Trados Studio\16\Plugins

You didn't say which version of Studio you are using so I based this on 2021.  Just adapt the location for whatever version you are using.

Thanks for your reply Paul!

The problem is with 2022 which I downloaded yesterday and installed. Now I see there's an update so I'm going to update to the latest build and will then get back to you. 

OK, installed the latest build (Trados Studio 2022 - 17.0.2.11672) but the problem is the same: it says I have to update the plugin and restart but I've done this about 20 times and the problem persists.

The other plugins are working fine. I find the "N/A" under Web Lookup! a bit strange.

The same message is in the Notifications, even after updating and restarting:

Here are the files I've found on the system; maybe the file size can help you to check the version.

The solution is here:
