I have Installed Photoshop CS5, reflection and everything was working fine, however when I am trying to click on Photoshop Help then I am getting an error message hat states "Adobe Air - This installation of this application is damaged. Try re-installing..". I tried to reinstall first Adobe Air and then uninstalled and re-installed Photoshop CS5, however the problem still remains. When I first attempted to use the Help function it attempted to upgrade or something and for several reason this failed. Please help me.
