You are allowed 2 activated copies of PS.  Since you did not deactivate PS before wiping drive Adobe still consdiers it an activated copy.  If you have this installed on another machine also there in lies your problem.

We are just users here.  You would have to call Adobe Custormer Service and explain your situation.  They can give you a number to fix problem.

Depends on if you have an activation problem becasue you have used up your 2 installs, or a Win8 problem.

Elbephoto, you really do need to call Adobe customer support to resolve activation issues.  No amount of registry manipulation is going to work around having used up your activations.  They're very nice and really will help you.  Don't eMail, don't chat - CALL.

I do know there's at least one person on this forum who is using Windows 8 (Kelly is I believe his name) and has gotten Photoshop activated properly.

I've been testing Windows 8 for the past several days (in virtual machines).  Microsoft has actually made it worse to use in the release version.  They've completely removed Aero Glass, for example, so now everything just looks flat and lifeless.  I've written a book that describes how to configure and augment the OS so as to get work done with it.  But I'm not sure people are going to want to upgrade to it wiith it looking this bad!

Have you tried removing Photoshop CS6 and using the Creative Suite Removal Tool to clean remnants of it up, then reinstalling?  I'm sure the telephone support people would have suggested that; I'm just confirming.

Only thing I can imagine is that Windows 8's UAC system is somehow getting in the way of Photoshop retaining its activation data.  It's no longer possible, using the Windows 8 UI, to completely disable UAC, though it is still possible to do it through registry manipulation (something best done by power users and system gurus).  If one does apps will no longer run in the "UI formerly known as Metro" - which suits me fine, but may not be good for most folks.

Have you tried running the installer As Administrator?

iPhone and iPad use an operating system called iOS.

Mountain Lion is the newest version of OS X and it runs only on a "real computer" like a Mac desktop or laptop.

Yes, I understand where Curt got the wrong impression that Mountain Lion is for iPads and iPhones as well as Macs, but it seemed best to let him know the facts.

I'm starting to regret trying to help.

You said, "... it appears that Mountain Lion was designed to work well with mobile units like iphone and ipad with less consideration given to a real computer... ".

I thought I was being helpful by letting you know that Mountain Lion is not designed for iPhone and iPad at all.
