My question is do I remove the demo version first before I download and install the SE version.
There's not usually any need to do that with Qimage, just "install over the top".
If I do remove the demo, I think I just right click and say remove program - correct?
No - we'll make you a PC person yet
To remove a program, from the Windows Start button, use Control Panel and for Vista, (I seem to remember you have Vista), choose Programs find whatever program you wish to remove on the list, select and choose Remove.
