Making Microtek ScanMaker 3600 Works in XP Pro ! Answered

I am moving my old scanner Microtek ScanMaker 3600 over to a new PC which runs XP Pro. However, the software (ScanWizard 5) doesn't "see" the scanner, although the PC "sees" it ! I have been fiddling with this thing for over 2 days now and still no result. The scanner does work. The XP Pro OS on the new PC "sees" the scanner, it's only the software that refuse to see it. I suspect it has something to do with the TWAIN driver on the XP. How to hack the stuffs??
