Article: Q315111
Product(s): Microsoft Home Multimedia Titles
Version(s): 
Operating System(s): 
Keyword(s): kbimu

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Encarta Reference Library 2003 - DVD Edition 
- Microsoft Encarta Reference Library 2002 - DVD Edition 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you try to install one of the Encarta Reference Library products listed at
the beginning of this article, you may receive the following error message:

  Error reading from file: <drive>:\<path>\DWINTL.DLL

where <drive> represents the drive letter of your DVD drive and
<path> represents the path to the Dwintl.dll file.

CAUSE
=====

This issue can occur if your computer has Universal Disk Format (UDF) disabled.

NOTE: Although UDF is not required to run the Encarta Reference Library DVD, some
DVD-ROM drives may have problems reading some DVD-ROM discs if UDF is disabled.

RESOLUTION
==========

To resolve this issue, use the following methods in the order in which they are
presented.

Method 1: Troubleshoot CD-ROM Read Errors

Base:

  Q218617 How to Troubleshoot CD-ROM Read Errors

If the steps in the article do not resolve the issue, proceed to the next
method.

Method 2: Enable UDF for DVD-ROM Drives
---------------------------------------

To enable UDF for DVD-ROM drives, follow these steps:

NOTE: Because there are several versions of Microsoft Windows, the following
steps may be different on your computer. If they are, see your product
documentation to complete these steps.

1. Click Start, click Run, type "msconfig" (without the quotation marks) in the
  Open box, and then click OK.

2. Click Advanced.

3. Click to clear the "Disable UDF File System" check box, and then click OK.

4. Click OK. When you are prompted to restart your computer, click Yes.

When your computer restarts, UDF is disabled and you should be able to install
Encarta Reference Library.
NOTE: By default, UDF is enabled in Windows. Therefore, another program (such as
CD-RW software) may not work correctly if you enable UDF. You may need to
disable UDF again in order for the other program to work normally.


Additional Troubleshooting Procedures
-------------------------------------

Use the procedures described in this section to further troubleshoot this issue:

Inspect the Disc:

Remove the disc from the drive and inspect the disc for damage such as warping or
large scratches. If the disc is damaged, contact the manufacturer regarding a
replacement CD.

If you experience problems with a DVD disc, ensure that you place the DVD in a
DVD drive not a CD-ROM drive.

Clean the Disc:

To clean the CD-ROM or DVD-ROM, use a disc cleaning kit, or gently wipe the
silver side of the disc with a soft, lint-free cotton cloth. Do not use a paper
cloth because it can scratch the disc. Wipe the disc from the center, outward.
Do not use a circular motion as this can scratch the disc.

If this does not resolve the issue, clean the disc using a water-dampened cloth
or a commercial CD or DVD cleaning solution. Dry the disc thoroughly before you
place it in the drive.

Test the Disc in a Different Drive:

If your computer has multiple CD-ROM, CD-R, CD/RW or DVD drives, test the disc in
the other drive. For DVDs, ensure the drive bears a DVD logo on the front. If
the disc works in another drive, the original drive may not be properly reading
the disc. Please seek help from your computer or disc drive manufacturer.

If the disc is clean and it does not work in another drive, it may be damaged and
you may have to replace it. See the section "Obtaining a Replacement Disc"
below.

Clean the Drive:

You can clean the disc drive using a CD-ROM or DVD drive cleaning disc, which are
available in most computer or home electronics stores. Before you purchase a
drive cleaning disc, try troubleshooting the issue using the remaining
procedures that are described in this section.

Test Disc Read with Copy or Xcopy:

Copy and Xcopy are command-line utilities that will usually uncover a disc read
issue. If Copy and Xcopy complete successfully, the issue is unlikely to be a
problem reading the disc. A failure to copy can indicate drive or system
problems and illustrate the need for further troubleshooting.

To test disc read using Copy and Xcopy, follow these steps:

1. Click Start, and then click Run.

2. In the Open dialog box, type "cmd" (without the quotation marks), and then
  press ENTER.

3. At the prompt, type one of the following commands:

   - To copy a folder:

  "copy <discdrive>:\<foldername><drive>:\psstest /V "
  (without the quotation marks)

   - To copy the entire disk:

  "xcopy <discdrive>:\*.* <drive>:\psstest /V /E " (without the
  quotation marks)

NOTE: <discdrive> is the drive letter of the CD-ROM or DVD drive,
<foldername> is the name of the folder containing files you need to access
on the disk, and <drive> is the letter of your system hard disk drive

4. Press ENTER.

5. If you receive a "Does psstest specify a file name or directory name?"
  message, press F.

6. If you receive an "Overwrite ... (Yes/No/All)?" message, press A.

NOTE: If you use the /V switch with Copy or Xcopy, the copied files are checked
to make sure that the files were copied correctly. However, the task may take
longer to complete if you use the /V switch.

Quit Unnecessary Software:

Software that is running on your computer may interfere with reading the disc,
for example, antivirus software, firewall software, or anti-crash software. If
you disable the unnecessary software, and then restart the computer, you may be
able to read from the disc.

unnecessary software, click the article number below to view the article in the

on the shortcut menu and you may need to click Quit, Close, or Disable depending
on the choices available for that program.

3. Press CTRL+ALT+DEL, and then click Task Manager.

4. In Windows Task Manager, click Applications.

5. No programs should appear under the Task list. If any programs appear, click
  to select the program, and then click End Task.

6. Repeat step 5 until the Task list is empty.

7. Quit Windows Task Manager.
