Installing Photoshop on Vista

I have been playing with the retail version of Windows Vista for a few days now and am pleased to report it has all gone quite smoothly, more on this later.
There is one slight annoying glitch – although Photoshop installs fine there is a registration dialog shown on each time the program is run. Even if you fill out the registration details it still appears the next time you start Photoshop.
To solve this problem do this: right click on the Photoshop icon and select “Run as administrator”, then either fill out the details once (or select “never register” if you already have). The registration screen will not be seen again.
