I see that a lot of people were looking for C105 PRO driver for win 95/98. This is a basically a win 3.1 TWAIN 16 driver. The installation should be very easy. The problem occurs when you use Photoshop or latest versions of Paintshop pro to scan images. Those programs require TWAIN_32 driver. So, the trick is very simple-get an older program (I use Paint shop PRO 2.01) which requires TWAIN_16 and then simply open scanned images in the software you narmally use. voila!
