Hello,
I have a Memorex 6142u scanner I am trying to run with Windows 7. Tells me I need a WIA driver. Have no idea what that is or where to find it. Can you help me?
You can try using VueScan (linked below). Your scanner appears to be rather old and apparently not directly supported by Windows 7. VueScan can help get some use out of older scanners. Worth a shot.
