Restart Windows in a modified mode | Windows 7, Vista - http://helpx.adobe.com/x-productkb/global/restart-windows-modified-mode-windows.html
Hope that Helps!
I do have other Adobe products installed (CS5.5 Master Collection, RoboHelp, Captivate, Lightroom, Presenter and Acrobat X) but I'm not about to uninstall them only to find out that when I reinstall them they won't work. So uninstalling them is a non-starter. I'd rather wait for CS7.
However, I uninstalled the CS6 Master Collection trial for the 5th time, ran the clean-up tool, followed the advice above, reboted, ran set-up as administrator and rebooted after the install only to find the same problem
Bottom line is that CS6ServiceManager.exe is not installing.
Any more advice would be appreciated.
Notice that no one supplies any responses after this stage.
Tsjanith you have responded to two fairly old discussions. If you are not seeing a resolution then I would recommend posting a new discussion. If you are facing errors when launching Photoshop then please post the details of the errors you are receiving in the Photoshop General Discussion forum.
