Questions:
Does installation of both Microtek Scanwizard pro and LaserSoft Silverscan conflict with each other?

dear jdwhite,

SilverFast and ScanWizzard have no conflict as long as the Microtek Scanner Finder is deactivated.

Please download the latest costfree version 6.4 for your scanner and install it.

Afterwards please delete once the LaserSoft Imaging folder.

On a typical Mac OS X installation, the " LaserSoft Imaging " folder is to be found at:
/ User / (your username) / Library / Preferences / LaserSoft Imaging
