Zipped file contains v. 1.18 of the 16 bit driver and v. 2.18 of the 32 bit driver. They are the self executing final editions from an installation cd. They install to Twunk.exe files in the windows folder. Just got to "choose input device" in your application and choose the Imagereader16 or 32. I've run both of these under Win 98 and 95 with great results. THIS 32 bit version has yet to crash on me like the prior ones!!
