Installation Path:
Start Menu
Computer
OS (C

(This could possibly be a different letter)
Program Data (If you dont see this, its probably hidden. Go to Start/Control Panel/Classic View/Folder Options/View and select Show Hidden Files & Folders)
Adobe
Photoshop Elements
6.0
Photo Creations
Photo Effects (This folder is used for this particular example. Depending on the action, you might choose a different folder to store it in. This choice will affect the way you access the action in PSE 6.)
Installation Technique:
Make sure PSE 6 is closed
Download action files from the source website to your computer. I usually download to my desktop and cut and paste the files to the appropriate folder (the Photo Effects folder in this case).
You should have one file ending in the .ATN suffix and one ending in the .PNG suffix. Each file should have exactly the same name, except for the suffix. If the names are different, right click on one of them to rename to the name of the other.
If you have a .PSD file instead of a .PNG file, open the PSD in PSE 6 as you would any other image. Go to the File menu, select Save As, and change the Format to PNG.
Open PSE 6 and open an image.
Look at the Effects Palette, usually on the right side of the screen. If the Effects Palette is not visible, go to the Windows menu and click on Effects.
Click on the Photo Effects button (3rd from the left under the word Effects). In the drop-down list to the right of this button, select Show All.
Click on the double arrow above the Show All box and select Show Names.
You should see a new thumbnail that looks like the PNG file you copied into the Photo Effects folder. (You can always open this PNG like any other image in Photoshop to see what it should look like in the Effects Palette.) This thumbnail will have the name of the action below it. If you cant find the new action, see Gotchas section below.
To run the action, double click on the thumbnail. Make sure an image is open and enjoy!
Possible Gotchas:
New action is not in Effects palette after restarting Photoshop:
Close PSE 6 and re-open it while pressing the shift key. Repeat steps 5 and 9.
If the action still isnt present, you will need to delete the MediaDatabase.DB3 file. Dont worry - Photoshop will rebuild it the next time you open the program. However, its a good idea to copy the file to your desktop as a backup, just in case something crazy happens.
To find the file, follow the installation path above, stopping when the 6.0 folder is open. From there, select Locale/en_us. Place a copy of the MediaDatabase.DB3 file inside this folder on your desktop, then delete MediaDatabase.DB3 file inside the en_us folder. (I assume that folks speaking the Queens English would select the en_gb folder, but I am not at all sure about this!)
Re-open PSE 6. It will open quite slowly this time as the database is being rebuilt.
If the new thumbnail still hasnt appeared in the effects palette, restart your computer.
If the thumbnail for the new action does not work when you double click it and there is a blank thumbnail with the name of the action under it, the name of your .ATN file and the .PNG file are probably different. Go back to the Photo Effects folder and make sure that the names are exactly the same except for the suffix.
