My HP ScanJet 5200c scanner software is non-HP supported and my install disk is unfindable. I'm on Windows 98SE w/a Gateway Pentium III. I have been using the scanner 3 yrs w/ no problems until June 07 then my scanner icon disappears off my device listing yet my programs HP PrecisionScan icon still appears and allows the copy and trial sample copy to print, but the HP "exe" click results with the HP Scan screen to appear followed by the message "unable to locate the scanner device". My properties listing shows there was a change made in June07, so I assume this has caused the error. So, I am seeking assistance to find another HP ScanJet Install Disk or downloadable software to restore my exe function. Any suggestions?
