Tried to download the updates and got a 404 error using the link.
Tried a manual search on the Adobe site, there are articles referring to the updates but the links lead you to the download page with no trace of the updates
Maybe a glitch? Will try again on Monday
If you only have the one computer to update then starting Photoshop going to Help->select the update software and it all happens automatically.
Download took around 5 hours yesterday...suspect that everyone was doing an update at the same time.
Printer dialogue now works better on Windows.
Still doesn't update the thumbnail in the layers dialogue when you convert to B&W through the adjustments menu (small niggle though).
