HP Scanjet 3400c under Vista
OK, I managed to get the HP Scanjet 3400c scanner working under Vista. This despite the fact that HP says it won't work. It does work. Here's how.
1. Download the XP drivers from the HP website.
2. You have to be running as administrator. (Check this under Start / Settings / User Accounts - you can see if you are administrator from there. If not, change your account type to administrator.)
3. You have to turn off UAC in Vista. See http://www.petri.co.il/disable_uac_in_windows_vista.htm for details about how to do this.
4. Find the driver you downloaded from HP and unzip. Don't just run it (it's an executable zip file). Just unzip it as if it were a regular zip file first. Then find the setuo.exe executable file. Right mouse it and select properties. Select compatibility and click XP service pack 2. Store and close.
5. Run setup.exe. The driver software will install.
6. Connect the scanner.
7. That's it. Works exactly the same as it used to under XP.
