I recently installed Creative Suite CS6 Design & Web Premium. I had previously installed the CS5 version and had not un-installed it. Everything except Acrobat appeared to install correctly. When I opened Photoshop CS6 (64-bit) I noticed that it used the CS5 version Bridge. I went into Bridge and unchecked the open at start box, closed Bridge and Photoshop and re-opened Photoshop CS6 (64-bit). When I tried to lunch Bridge from Photoshop the following message appeared in the Desktop> panel : Waiting for Bridge CS6..." Bridge CS6 did not appear despite waiting for several minutes. I then pressed the Start button and went into the Programs listing. Under the Adobe CS6 group I found all of the applications (other than Acrobat) but Bridge CS6 (64-bit), Bridge CS6, and Media Encoder each had generic icons rather than the expected relevant Adobe icons. I tried to load each of the three by clicking on the icon. In each instance the following message appeared:
The version of this file is not compatible with the version of Windows you are running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program and then contact the software publisher.
My system is a Gateway FX6802. I am running Windows 7 Home Premium version 6.1.7601, Service Pack 1, Build 7601. The system has 9 GB of memory. I ran CS5 on the system and did not experience any difficulty with Bridge.
