I just signed up for Adobe Creative Cloud. Dreamweaver and Flash initiated flawlessly - got a license agreement screen, agreed to terms and they launched. When I did this with Photoshop 64bit, after the license screen i got this message "Cannot complete your request the internal file signature is incorrect." Trying again just bypasses the license screen and goes direct to the error message.
What is Adobe's error and how can I use Photoshop?
Win 7 Pro, 64bit, 24GB RAM
Thanks
