Hello! My name isXXXXX will work diligently to provide accurate advice and information.
There was a common issue with PSE 10 and Lion hat may apply here. The permissions issue does not directly relate to the app itself but rather a support folder.
In the Finder, click the Go item in the menu bar at the top of the screen
Hold down the Option key on your keyboard and select Library
Once you are viewing the Library, open Application Support.
Select the Adobe folder and then right-click or Control-click to choose Get Info from the context menu.
Under "Sharing & Permissions", click the lock in the bottom right corner and enter your password XXXXX unlock the panel.
If your name isn't in the list, click the "+" sign to add it.
If the user name is XXXXX XXXXX with "Read" permissions, click the arrows and select Read & Write.
Next, click the 'gear' icon and select "Apply to enclosed items"
If all goes well, you should then be able to run PSE.If you still have concerns, please do not negatively rate my answer, simply reply back before rating. I'll be more than happy to work with you further
