My bad. Generally speaking, you will need drivers specific for the computer you will be using. Generally speaking it's a good idea to use a scanner that's designed to natively "play" on that computer.
I looked and I could find little in way of support for the Canon FS-2000
If USB try Vuescan Hamrick.com Does not need TWAIN driver works with most may be all USB scanners Amazing capabilities ! Free to try, purchase gives you lifetime upgrades My favorite
