Is there ANY free scanning software I can use with my plustek 8100?

Got a plustek off eBay! USPS managed to send it all over kingdom come and it arrived a week late. Now I’m having to deal with transferring the silverfast SN and having to wait another whole week to while the company sorts that out. I’m really eager to scan some pictures. Is there literally any software I can use to get some scans for free while I wait ? (Without watermark obvi)
