Works on the lap-top but not the desktop - trouble is not the card, the reader, or the software. How old is the desktop. I don't know if the reader requires a 2.0 or higher USB, and may not work with the older 1.0. But you have Win 7, so Your computer must not be that old. Try something else in that USB slot, but that has to be the problem.
