I have been using the Fujitsu ScanSnap scanners for a long time now. Today Fujitsu announced that they have a brand new 64-bit version of their scanner software. This comes as a relief to users that have been getting the 32-bit software warning. I've been using the 64-bit software for a while and had no issues. Interestingly, this is not an upgrade to the existing software but a brand new version of software that you’ll need to download from this link.
