ADDITIONAL NOTES (NOT IN TORRENT INSTRUCTIONS);

IN WINDOWS VISTA AND WINDOWS 7 WHEN YOU FIRST START PHOTOSHOP AFTER INSTALLING YOU NEED TO RUN IT AS ADMINISTRATOR TO ENSURE ALL PERMISSIONS ARE SET. YOU ONLY NEED TO DO THIS THE FIRST TIME YOU START THE APP.

BY DEFAULT PHOTOSHOP WILL INSTALL 32 AND 64bit VERSIONS ON 64bit WINDOWS, IF YOU ONLY WANT THE 64bit INSTALLED TO SAVE DISK SPACE AND IMPROVE PERFORMANCE THEN FOLLOW THESE STEPS;

1. Run the Photoshop CS4 installer.
2. Enter your serial number. Click Accept.
3. On the right side of the Options panel under the 64-bit heading, uncheck the 
 box for Adobe Photoshop CS4 (leave the Adobe Photoshop CS4 (64-bit) option 
 checked).
4. Finish installation.

DO NOT INSTALL PHOTOSHOP TO A CUSTOM LOCATION IN ANY 64bit OPERATING SYSTEM.
