Just to add a little info to this thread...
I have the Win95 and Win97 software and it works very well. I also have the Butel software for the Pro-2051 and the BCT15 and it is excellent. I have the ARC15 Pro for the BCT15 and really like it. Money well spent. The web import feature of the Butel and the Starrsoft software is great. Not always perfect but gets you 99% of the way there.
Now onto Scancat lite. I recently purchased that software and just hate it. Buggy, bloated, and just ugly. Nothing 'lite' about it...uses 80MB of RAM before you even open a profile. Worst. Scanner. Software. Ever. I would really suggest avoiding it if you can.
