    Download link: DirectX Test Tool ( V.r 1.2, 70Kb)
  2. Double click the file to start the program.
  3. Click the "View DX Info" menu item.

Action Descriptions

  • View DX Info - Will run the following tests on your computer.
    • Searches the Windows registry for key HKey Local Machine\SOFTWARE\Microsoft\DirectX,Version= . If found and the Version value is correct then DirectX 9.0c is installed.
    • Will look for the date of DirectSound dll (dsound.dll MUST be dated March 2008 or later). This check is valid on XP only. On Windows® 10/8/7 , dsound.dll may be inside a CAB file.
    • Will attempt to initialize your detected sound devices for DirectX. A result of "Initialized=False" indicates the init failed. Failed init may indicate a problem with the device. Check for device errors in Windows Control Panel -- System -- Device Manager . Or the device may not have a DirectX driver which is normal for some devices (ex. a dial-up modem card with a speaker).
Best Practice: In some cases, even when DirectX 9.0c is installed, it may have a corrupted or missing file(s). We recommend you install the latest release of DirectX 9.0c which may fix DirectX errors and may provide security and performance enhancements.
