I have an old Microtek scannmaker X6EL that refused to work "twain error" the driver appeared to be fine just refused to scan through any programs. I found this program VueScan that worked prefectly. This program is not free but beats buying a new scanner. You can use the program to test for free but until you purchase it puts a watermark on scanned images. If anyone has a better solution I would be interested. Still can't get it to work with fax & scan although it shows up as working in device manager fax & scan say no scanner attached. Thanks and hope this helps.
