This page is for the retail version. For the Space Cadet table bundled with Windows XP, see 3D Pinball for Windows - Space Cadet.
Patch 1.01 (#2) will update retail versions to the latest version.
The original installer for Full Tilt! Pinball is 16-bit, and therefore incompatible with 64-bit versions of Windows. In addition, the installer is incompatible with Windows NT-based operating systems, meaning Windows XP and later are unable to run the installer. A fix is available, which bypasses the installer altogether, instead using batch files to start the games.
