I have successfully installed Photoshop CS5 on a laptop running Windows 8.1. When I attempt to update Photoshop (Help >Updates . . .) I get this error message:

The update server is not responding. The server might be offline temporarily, or the Internet or firewall settings may be incorrect. Please try again later.

I do not get this message when I select Updates on my Windows 7 computer, and I did not get it when I installed Photoshop CS5 on a different laptop running Windows 8. (I uninstalled it from that laptop.) I have tried turning the firewall off, but that did not help.

Any suggestions would be appreciated!
