Also try to launch the game, then open Task Manager (Ctrl+Alt+Del by default) and check for processes toy2.exe and rundll32.exe.Right click on toy2.exe - Properties - Compatibility - Set 'Run this app in compatibility mode with Windows 95/98, Windows 2000 or Windows XP'. If the game doesn't run - open the directory with the game and find toy2.exe. After you installed the game, install Toy Story 2 Fix (simply extract all files to the game directory).Also it is recommended to install DirectX from the disc (inside the disc image in 'Setup' - 'DirectX' folder).You will need the utility for mounting disc image files, like WinCDEmu, UltraISO, Alcohol 52%/Alcohol 102% or Daemon Tools Lite
