This article was previously published under Q154908

SYMPTOMS

You may receive a "File Not Found" error when attempting to view video or graphic files in Mastering Microsoft Access Programming.

CAUSE

This problem occurs when the application is unable to open files on the CD-ROM for binary input in order to extract size information out of the file header. This process fails when either no drivers are installed or only Real-mode drivers have been installed for the CD-ROM device.

RESOLUTION

To verify that your computer is running Protect Mode CD drivers, follow these steps:

  1. Click the Start button, point to Settings, and then click Control Panel.
  2. Double-click the System Control Panel.
  3. Click the Device Manager tab.
  4. Examine the list of devices under Computer. If CD-ROM appears in this list, then you are running Windows 95 Protect Mode drivers.
To remove any existing Real Mode CD drivers, follow these steps:

  1. Click the Start button, and then click Run.
  2. In the Open field, type sysedit, and then click OK.
  3. Examine the Autoexec.bat file. Look for a line referencing the file MSCDEX.EXE. For example:

    C:\WINDOWS\COMMAND\MSCDEX.EXE /D:CDROM01

    Remark out this line by placing "REM " at the beginning of the line.
  4. Examine the Config.sys file. Look for a line containing an identical string to the "/D:" string identified above. For example:

    DEVICEHIGH=C:\CDROM\IDECD.SYS /D:CDROM01

    Remark out this line by placing "REM " at the beginning of the line.
  5. Exit the System Configuration Editor. When you are prompted to save your changes, click Yes.
To install Protect Mode CD drivers, follow these steps:

NOTE: If your computer is already running Protect Mode CD drivers, the following steps are not necessary.

  1. Click the Start button, point to Settings, and then click Control Panel.
  2. Double-click the Add New Hardware icon.
  3. Allow the Add New Hardware Wizard to detect your CD-ROM device.
