Thats what i thought, Dont install brand new Xampp, copy the old installation back to c:/xampp or similar.
You might try to replace the data folder of mysql in your brand new Xampp instead, rename the original folder (like data-backup or so) and copy the old mysql/data folder to the new Xampp installation. If you are lucky, this already works. But if your previous installation was too old, this does not work properly, therefore i recommended to restore the old Xampp installation as well. But you may try this of course.
