The SD card in the scanner are probably corrupt but the EZScam program should start and be operational without you trying to access the scanner. Install it to another folder on your computer, to a normal harddrive, no network drives or other non standard drives and see to that you login as the admin of your computer.
If you do not have a $5 SD card reader, get one and format the SD card and prepare and program only using the SD card reader, not in the scanner.
