I hope someone out here can help me.  I'm a Creative Cloud user.  I have been using the 64-bit version of Photoshop 13.0.x on my system successfully for several months now.  I have Windows 7, 3rd gen (Ivy Bridge) core i7 processor, 32GB of RAM, a 1TB Hard Drive, and am using an NVIDIA GeForce 670 video card.... so my system has plenty of processing power.  Several nights ago, my Adobe application manager pops up on start up (as normal whenever there's app updates to be done) and says there's an update available for Photoshop (version 13.1.2, I think.. or something close to it, anyway) and Bridge.  So, as normal, I apply the updates... Everything completely successfully according to the Applicatino Manager.  However, when I try to start photoshop after the update, I get this window that pops up immediately upon double-clicking the Photoshop 64-bit icon on my desktop: "Adobe Photoshop cannot run on this computer because this version of Photoshop requires Windows 7 or later."  All I can do is "X" out the box to make it go away, so I did.  Weird because obviously I have Windows 7 and all of my other software works great on my system, and I have Lightroom 4.3, other Adobe stuff, Serif software, ACDSee, etc... and I get no problems out of ANY of them running on my officially licensed version of Windows 7.  So just for the heck of it, I uninstalled Photoshop completely and then reinstalled it using the Adobe Application Manager.  It installs version 13.0, which then allows me to open and use Photoshop as normal.  I proceed to "check for updates" from within the program, and it takes me to 13.0.2 I believe.  I can use Photoshop as normal after that.   Here's what I think is funny... I can check for updates to my heart's content after updating to 13.0.x.  The program thinks there's no updates available after 13.0.x.  The only way my system knows there's a later version out there is if I power down my system and restart it.  Then and only then will Adobe Application Manager come up and tell me there's an update available (13.1.2) which, if I chooose to install (and I did), takes me back to the error that I mentioned earlier: "Adobe Photoshop cannot run on this computer becuse this version of Photoshop requires Windows 7 or later".  Soooo with all of this said... DOES ANYONE know how the updated version of Photoshop (13.1.2) for Creative Cloud Subscribers checks to see if it's running on a Windows 7 system?  For whatever reason, it doesn't think I have Windows 7 after updating to it, and I'm stuck!  I know if I contact Adobe Support, they're going to want to uninstall ALL of my Adobe software of which I have alot, and then reinstall everything... and quite frankly, I think all that is a bunch of crap!  It's plain and simple... Photoshop works BEFORE the update, and will not open due to this error AFTER the update, so there's some issue with the updating procedure that causes Photoshop to not recognize my Windows 7 system, and I just pray that SOMEBODY out there might be able to help me change some setting on my system that will cause Photoshop 13.1.2 to actually work!
UPDATE: I decided to check the 32-bit version of 13.1.2, and it works!  So it looks like this error is limited to the 64-bit version.  That just makes no sense at all to me.
