CS6 64 hangs-why?

Question

Just installed Photoshop CS6 Extended on two 64 bit Windows 7 machines. One went fine--a clean install on a workstation with no prior CS versions.
Second machine, a laptop,  not so good. The 64 bit version hangs as soon as I try to open a file, even using File > New. The program is totally hung and nonresponsive at that point. But the 32 bit version works fine.
Both machines are running 64 bit Win 7, SP1, autoupdated. The second machine had Photoshop 7 and Photoshop Elements 8 still present when I first installed CS6. When the 'hang' first happened, I uninstalled both, and then reinstalled CS6. Problem persisted. Unistalled and reinstalled CS6 again after reboot. Problem persisted.
VERY irritating, Adobe.

Wow, crazy all of this you're having to go through.
Along with the Cleaner Tool(s), I make it a habit of going through and actually wiping out the prefs (mentioned above) along with any other Adobe related files.
These can often hang around in places you'd never think to look, like "AppData/Roaming, Local, Low".
There are also specific ARM files that track what's installed, registered, etc.
One more question, is the installation being carried out from a disc?
Is it being installed from a download?
In that blog post I mentioned, one time a tech. rep advised me to copy the contents of all directories of install discs onto the local drive of the machine.
There was a bug with payloads not being able to be accessed properly when installing from a set of directories on a disc.
Strange that you never recieved errors though.
On the last upgrade cycle, these were apparent, but may be hidden now.
There were even support docs citing these codes.
Are you using Windows Home Premium 64-Bit or Pro?
