Infact it's a twain driver but scanner works with TWAIN supported softwares e.g. Adobe Photoshop (File>Import>Twain) Command.
There are two files Disk-1 & Disk-2, The needy must download the both. Disk-1 Zip contains Setup.exe then setup'll ask for the 2nd disk. I think who can search can do further.
BEST OF LUCK
The following files are found inside the driver download file.
