Cannot Play .avi Files with Number 9 Video Card

Q137051

---

The information in this article applies to:

• Microsoft Windows 95

---

SYMPTOMS

When you upgrade from Windows 3.x to Windows 95 on a computer with a Number 9 video card, you may receive any of the following error messages when you try to play .avi files or run a program that plays .avi files:

• Invalid dynamic link call to a .dll
• Page fault in mmsystem.dll
• This program has called an invalid dll
• Your program is making an invalid dynamic link call to a .dll file

CAUSE

Some Number 9 video card drivers for Windows 3.x add support for DCI functions that can conflict with the DCI support in Windows 95. When you upgrade to Windows 95, the previous Number 9 DCI support is not removed.

RESOLUTION

To correct this problem, follow these steps:

1. Use any text editor (such as Notepad) to open the System.ini file in the Windows folder.

2. In the [Drivers] section of the System.ini file, change the line that reads

   DCI=RFMDCI

   to read:

   ;DCI=RFMDCI

3. In the [Display] section of the file, change the line that reads

   DCI-Support=On

   to read:

   ;DCI-Support=On

4. Save and then close the System.ini file.
5. Shut down Windows 95 and restart your computer.

NOTE: Most Number 9 video cards also change the "DCI=" line in the [Display] section of the System.ini file. Changing this to read:

DCI=Display

This solves invalid dynalink problems when you run .avi files.
