The "problem" is not a problem and has nothing to do with this installer. Its photosop wanting to install the original vc10, it fails because there is a newer version installed, then it craps out... Other than removing the latest runtime and replacing it with rtm I cannot do anything about this, you will need to uninstall the latest, install photoshop, let it install older runtimes, uninstall those and re-run this installer with /aiX to ONLY install the vc10 runtimes
