1. Disable all virus-protection software.
2. Ensure that the folder on your hard disk containing Photoshop is named "Adobe Photoshop CS5." 

3. Double-click the "AdobePatchInstaller" application. If the updater reports that it cannot find the application to update, uninstall Photoshop CS5 or CS5.1. Then, reinstall the application (use the default folder name "Adobe Photoshop CS5"). To uninstall Photoshop on Windows, navigate to the Applications/Utilites/Adobe Installers folder and run Add or Remove Adobe Photoshop CS5. When the uninstallation is complete, reinstall Photoshop, and then run the updater. 

4. Follow the onscreen instructions.

This updater updates only the retail version of Adobe Photoshop CS5 or CS5.1 and not any prerelease (beta) versions. To confirm that the updater has run successfully, launch Photoshop. Verify that the version number on the startup screen shows 12.0.5 and not 12.0.0 for Photoshop CS5, or shows 12.1.1 not 12.1.0 for Photoshop CS5.1. If it does not show correctly, it's possible that you don't have a retail version of Photoshop CS5. Contact your local Adobe retailer or visit the Adobe website to purchase one.
