I am trying to install Neatworks 4.0 2 button mobile scanner on my HP Pavilion Laptop running XP Professional Service Pack 3. The computer briefly recognizes the scanner with "New hardware found" then immediately says " a problem has occurred during installation" and the scanner disappears from the system tray and a yellow asterisk appears in device manager. I have reinstalled many times after deleting every Neatworks file I could locate. Still can't find the scanner.
