The information in this article applies to:

SYMPTOMS
========

If you click Scanner Image on the Insert menu, and you then click Select
Scanner, one of the following may occur:

 - The list of scanners in the Select Source dialog box is blank.

   -or-

 - You receive one of several error messages.

CAUSE
=====

In order for Scanner Image to be available on the Insert menu, the
following must be true:

1. There must be a folder called Twain located in the Windows folder.

2. There must be a file with a .ds extension either in the Twain folder
   or in a folder inside the Twain folder it.

However, in order for the command to actually work properly, the
following additional criteria must be met:

1. The .ds file must be a TWAIN scanner driver. If this driver requires
   any additional files, they must be installed properly.

2. The following files must be installed in the Windows folder:

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

   These files must be either the version of the driver that ships with
   Publisher or a later version.

RESOLUTION
==========

Check the Properties for the four files listed. The files that ship with
Publisher have these properties:

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

File size      82,848        110,592          46,752         67,584
Date          8/16/95        8/16/95         8/16/95        8/16/95
Version       1,5,4,6        1,5,4,6         1,0,0,6        1,0,0,6

All four of these files should have the same date, and the version
numbers should be the same or higher than the ones listed.

the previous table, do the following:

1. Rename or delete these files on your computer.

2. Run Control Panel and double-click Add/Remove Programs.
