Why bronze medal for this application?
Installer doesn't work and application does neither work with all tutorials used. Seem to be the wine binaries in Crossover, because with the original current wine binaries (1.3.20) does work with the tutorials (Installer neither works there).
So since it is allready working in wine, you could perhaps get it working also soon.
I used this tutorial http://maketecheasier.com/install-photoshop-cs5-in-ubuntu-maverick/2010/11/02/ to get it working.
