This driver was made for the Artec AM12s Scanner - but it will work with Windows XP (pro) and the Plustek Optic pro 19200s, too!!!
Just follow the instructions in the file "XP alternate solution.doc". Maybe you'll need the "stivs32.dll" - it's also included in this zip-file.
Hope I could help you!
Ah, I forgot - You MUST choose the driver for the AM12s Scanner, because only then your Plustek scanner will work fine!!!!!
Naturally I will answer e-mails how good I can (also in german!)
Have fun with your working scanner under XP!
