16 Matrox Graphics Card – Installation Guide
Problem: Game for Windows 95 doesn’t start or runs slower than normal
(program uses Microsoft DirectX interface)

An older version of DirectX may be installed. The “Matrox Installation” CD-ROM setup
program installs DirectX as part of the MGA PowerDesk software installation, but some programs
install an older version of DirectX (overwriting your version). To see what version of DirectX is
installed:
1 Right-click the Windows desktop background, then click Properties  Information.
2 Look at the Microsoft DirectX Version label.
If DirectX 5.0 or later is not installed, follow the instructions below.
Solution
Install DirectX version 5.0 or later. To install DirectX 5.0:
1 Insert the “Matrox Installation” CD-ROM in your CD-ROM drive. Windows automatically
starts the CD-ROM setup program; click
Cancel to continue.
2 Click  Run.
3 Type “d:\directx5\dxsetup”, where “d:\” is the drive letter of your CD-ROM drive; then click
OK to start the DirectX setup program.
