Finding uninstalled software

[Hochman]

I uninstalled an HP all-in-one which I was using for scanning and installed a Canon. My application has a 'scan' feature. When I click it, it says 'Cannot communicate with HP scanning'. It seems that there must some HP code somewhere. Help!

HI,

This problem come from your TWAIN driver wich has not correctly uninstalled.

You can remove it manually from the windows\twain_32\ directory.

Best regards,
