Driver za skener v visti?

Run the self-extracting .exe (uncheck "When Done Unzipping Run: Setup.exe").

Go to the new directory, open the properties dialog for Setup.exe and select XP SP2 compatibility (this isn't necessary for all installation packages, but
it's necessary for this particular package)

Run Setup.exe

Connect a USB cable and turn on the device

Allow Vista to "Locate and install driver software..."

Select "Install Anyway" when it warns of an unsigned driver (this is perfectly safe in this case because it uses the in-box usbscan.sys driver)

So, in general, follow the same steps you would on XP.
If the setup program fails, try enabling the XP SP2 compatibility (through the properties dialog for the Setup.exe file).
