Friend using Windows Vista. Had a scanner that worked ok for several months
without issue on his Vista maching. All of a sudden he gets the folowing
error
"Twain error (T009) error opening twain data source.Unable to find the twain
source manager (Twain.dll ) Please copy the twain.dll file from your source
disk to your windows folder."
He is using Ulead Iphoto plus 4 software, and his scanner is a HP Scan Jet
4370. It
worked correctly on XP.
After getting the Vista machine he downloaded the new program and drivers
form HP to use with VISTA.
He is puzzeld why it stopped working on the VISTA machine so abruptly?
Any ideas?
TIA
