So ever sense I've owned a Mac I've been told that to simply remove any software you just have to delete it out of the Appilcations Folders. That would appear to be false, I did that with Photoshop CS6 Beta. Now that I am trying to install Photoshop CS6 Trial it keeps giving me an error that says that there is a version of CS6 on my computer already. Does anyone know how to find the hidden files or atleast the file that the installer is seeing?
Please first try running the uninstaller in Applications/Utilities/Adobe Installers. Once that is done you can utilize the clean up tool by following the directions at CS Cleaner Tool for installation problems | CCM, CS6, CS5.5, CS5, CS4, CS3 - http://helpx.adobe.com/creative-suite/kb/cs5-cleaner-tool-installation-problems.html. This should remove any additional components.
In regards to uninstalling on Mac. Many applications are able to utilize the package feature to contain all of their components. Do to the shared components between Adobe applications and their multi-platform nature we utilize an uninstaller. This is because we do not contain all of the files required for the application within the package for the application itself.
