Our Microtek i900 has been almost impossible to wrestle under control using Microtek's PHENOMENALLY badly designed ScanWizard software.
Starting off, when you install the software, it actually creates a folder called "Applications" - in the primary user's folder! Helloooooo?
After you've wrestled with ScanWizard for enough hours of sudden crashes, impossibility of getting the TWAIN drivers to work importing directly into Adobe CS3 apps, you might be tempted to run the "Uninstaller" which Microtek sees fit to install with every installation.

Let's see - if I were going to automatically install an uninstaller, I wonder... would I also contemplate the fact that perhaps some users are uninstalling in order to attempt a clean install? If so, I might be tempted to have the uninstaller actually UNINSTALL THE APPLICATION. Which it will do, provided you've left in the unecessarry Scanwizard folder it created in your Applications folder, which - you guessed it - contains the application, and the uninstaller!

Then, it might be a good idea if the uninstaller actually removed the plug-ins it's placed in the Adobe CS3 apps' plug-in folders, the Application Support files it's installed, and last but not least, six or seven preference files for "Microtek" "ScanMaker" "Scanwizard" a bunch of other stuff.

This semi-workable scanner is hobbled by the lamest software ever attempted by a company who obviously run Windows EVERYTHING, bought one Mac (a used iMac, I'd guess) and tried to build software for it.
