SYMPTOMS
When you try to install one of the Encarta Reference Library products listed in the &quot;Applies to&quot; section, you may receive the following error message:

Error reading from file: :\ \DWINTL.DLL

In this example,  represents the drive letter of your DVD drive and   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 read errors
For more information, click the following article number to view the article in the Microsoft Knowledge Base:

218617 How to troubleshoot common problems that occur when a Windows 98-based or Windows Millennium Edition-based computer cannot read a CD or a DVD

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

Method 2: Enable UDF for DVD drives
To enable UDF for DVD 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 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, make sure that 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 &quot;Obtaining a Replacement Disc&quot; 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:  Click Start, click Run, type cmd, in the Open dialog box, and then press ENTER. At the prompt, type one of the following commands:  To copy a folder:

copy :\  :\psstest /V

 To copy the entire disk:

xcopy :\*.*  :\psstest /V /E

Note In this example,  is the drive letter of the CD-ROM or DVD drive,   is the name of the folder containing files you need to access on the disk, and   is the letter of your system hard disk drive

  Press ENTER.</li> If you receive a &quot;Does psstest specify a file name or directory name?&quot; message, press F.</li> If you receive an &quot;Overwrite ... (Yes/No/All)?&quot; message, press A.</li></ol>

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.

After you have performed a clean boot of Windows XP, close any remaining programs by following these steps:
 * 1) Quit all open programs.
 * 2) Right-click each icon in the notification area, and then click Exit.

Note The notification area is located at the far right of the taskbar, near the clock. Some programs listed in the notification area will not have Exit listed on the shortcut menu and you may need to click Quit, Close, or Disable depending on the choices available for that program.
 * 1) Press CTRL+ALT+DEL, and then click Task Manager.
 * 2) In Windows Task Manager, click Applications.
 * 3) No programs should appear under the Task list. If any programs appear, click to select the program, and then click End Task.
 * 4) Repeat step 5 until the Task list is empty.
 * 5) Quit Windows Task Manager.

Switch the drive controller to DMA mode
If you switching the CD-ROM or DVD drive to DMA from PIO, you may resolve the issue. For more information about how to switch your computer's drive controller to DMA mode, click the following article number to view the article in the Microsoft Knowledge Base:
