I had the same error. Im running on a 64 bit system. I found the error came up because i had altered the default installation path in the registry (i use an ssd as well). As soon as I put it back to defaults (pic is attached for your reference) Photoshop 64bit opens with no problems but when I change it again, the same error comes up. Make sure you take a backup of your registry before you edit it! Make sure that your registry matches mine then it should work.
Hope this helps someone
