When you run Adobe Update Manager, install the Camera Raw plug-in, or reinstall a Creative Suite application such as Photoshop CS5, the following error appears:
"Installation cannot continue until the following applications are closed: Adobe Bridge."
In Windows, right-click the Bridge CS5 or CS4 icon in the Notification Area of the Start Bar in Windows, and choose Exit Bridge. If you still cannot close Bridge, open the Task Manager by pressing Ctrl+Alt+Delete. In Task Manager, choose Bridge and select End Task.
In Mac OS, Ctrl-click the Bridge CS5 or CS4 icon in the dock and choose Quit.
In Windows, right-click the Start Bar and choose Task Manager. Select the Processes tab, and choose to end the Bridge.exe process.
In Mac OS, choose Apple menu > Force Quit, and choose to close Adobe Bridge.
Note: Solutions 1 and 2 allow Adobe Bridge to continue to start at login.
This error occurs when Adobe Bridge is configured to start at login, so it is running in the background when you install your application or plug-in.
Restarting the system doesn't solve this problem unless you perform Solution 3 first. For more information, see the Bridge Help topic Start Adobe Bridge automatically.
