Thanks for this reply. Not condescending at all.

Yes, when I fire up my Lightroom 5.4 it more or less immediately comes up with the window

=============================================

5.5

• Support for syncing star ratings and custom sort order to Lightroom mobile and Lightroom web.
• Fixes for bugs introduced in earlier versions of Lightroom 5.
• Camera support for additional new lenses and cameras.

Current version : 5.4 (build 955652)

=============================================

and at the bottom right of that window there is a Download button. However, when I click on that it takes me to Adobe - Lightroom : For Windows : Adobe Photoshop Lightroom 5.5 but when I select "Lightroom" on that page it takes me to Photo editor app | Download free Adobe Photoshop Lightroom 5 trial which contains acres of Lightroom ads but no "Download" button apart from the "Free trial".

I've been looking around to see whether my Firefox is blocking something but no success there. I also tried it with Windows IE. Again, no success.

I'm flummoxed.
