PUB98: How to Reinstall Scanner Software

MORE INFORMATION

To reinstall the TWAIN components, follow these steps:

1. Remove the following files from your \Windows folder:

   Twain.dll
   Twain_32.dll
   Twunk_16.exe
   Twunk_32.exe

2. Remove the \Windows\Twain folder and all of its contents. This folder contains a proprietary library file that is installed with your scanner software and has a .ds extension.
3. Install the software that came with your scanner to its default location. This should replace the .ds file.
4. Test the scanner software, by itself, to see if it works. Try scanning a picture directly into Publisher. If the test is successful, you are done. If the test fails, go to step 5.
5. Run Publisher Setup. When the Maintenance Mode dialog box appears, click Reinstall. This step will replace the TWAIN and Twunk files that you removed in step 1.

If you are still unable to scan directly from your scanner into Microsoft Publisher, then Publisher is probably not compatible with the TWAIN interface of your scanner.

NOTE: TWAIN (which stands for Technology Without An Interesting Name) is a standard protocol that allows many different kinds of scanners and digital cameras to work with many different software programs. It is developed jointly by a number of companies, including Logitech and Hewlett-Packard.
