I just upgraded to CS4 and am trying to load the new ACR 5.6. The setup keeps saying I must close Bridge even though it is not open. I even sent Bridge to the recycle bin but it still says Bridge must be closed. Anyone have this problem?
I fiund the answer on the Adobe forumn. Somehow Bridge got into the Startup Menu and was running as a stealth program in the background. Once I took it off the Startup menu, ACR 5.6 loaded fine.
