I am setting up a standalone laptop (not attached to the network) with MSWindows XP in order to use a Scanjet 7400C with it's transparency adapter. I have the impression I have to install it's drivers, the Precisionscan Pro software, and all the subsequent patches in a specific order. MSWin XP sees the scanner with no problem, but Precisionscan says it can't see the scanner. It's been like that on various setups I've tried, including inside a VirtualBox VM (which would be the preferred method, but Precisionscan is unreliable there at best)
These are the files I have:
COL10439en.exe
HP Scanjet 7400c Windows.iso
setup_basic_7400.exe
sj596mu.exe
sj668en.exe
sj677en.exe
sj678en.exe
sj679mu.exe
sj700en.exe
sj709.exe
So which files should I use for WinXP, and in which order?
