Not to get too far OT Just Shoot Me, but the scanner driver has _everything_ to do with the version of PS req'd. Canon's scanner API (and pretty much everything else) is notoriously proprietary. Its not fully supported by most third party scanner software now, and wasn't at all many years ago. So the _only_ option to get full feature support was to use their driver. More importantly, the last time I looked even solid options like Silverfast (which still only offer "32-bit support") had _no_ support for FARE (Canon's version of Digital ICE) and not having this was simply _not_ an option. The only driver Canon ever released for the 9950F was a 32-bit version, and this _requires_ a 32-bit application, hence my need for the 32-bit PS for importing scans. In this regard my copy of PSE 4 is _far_ superior to the current PS 19.0.
