ok,...your os detected the scanner,..thats good,..what bad is that file...i don't know what this file is either,...whether its a system file or not.
if its an installation file,..you can just get installation files files from the manufacturer or something,..download fro their website or other sources in the net.
if the scanner worked( meaning it installed w/o problems) in other similar system(same os), then then its a system file...if this is the case you might want to reinstall XP...or do diagnostics with the OS(find if anything else is not working correctly).
whats the scanner a.... 6600,..thats HP right?
