WINDOWS TIPS AND TRICK

1. Click 'Start' and select 'Computer' or 'My Computer.' Double-click your hard drive, typically your 'C' drive, and double-click to open the 'Windows' folder. Locate the 'Twain' sub-folder and search for the following four files: 'Twain.dll,' 'Twain_32.dll,' 'Twunk_16.exe' and 'Twunk_32.exe.' Right-click each of the files and select 'Delete.'
2. Right-click the 'Twain' sub-folder in the 'Windows' folder and select 'Rename.' Type any name you choose and press 'Enter.' Repeat this action to rename the 'Twain_32' sub-folder, also located in the 'Windows' folder. This folder contains a proprietary library file that installed with your scanner software. It has a .ds extension.
3. Insert the installation disk for your scanner into your CD/DVD-ROM drive. Follow on-screen guided prompts to complete installation of your scanner software to its default location. This re-installs the TWAIN components.
