I am running under Windows 98.

Having had problems with the Scanjet button manager, I removed all hardware and software from my system and went back through the whole installation process in the right order, including physically reinstalling the SCSI card. The PC recognises the card but then fails to find the driver for the scanner. Eventually I got the message "Error in REG32.DLL Missing Entry: UpdateButtonSupport"

When I fire up the scanning software it doesn't find the scanner. I've tried the suggestion from the HP FAQ's of disabling HP Button Manager from the systray without any benefit. I'm lost - any bright ideas ?
