Installed IntelliPoint 7.00.204.0 on my #2 system running Win7 RC. Mouse is IntelliMouse Explorer - detected and software installed ok.
Installed IntelliType Pro 7.0 on my #2 system with Win7 RC. Keyboard is Microsoft Natural Keyboard Pro - not listed as a selectable item during setup - Cancel selected.
Verified software removed from Program Files.
Decided to try IntelliType Pro version 5.50.661.0 which had worked on XP Pro - would not install compatibility issues. Cancelled setup.
