To get IntelliPoint running on Vista:

1.. Grab the latest version of the Microsoft IntelliPoint software.
2.. Run setup, it will extract the files and folders to C:\Program Files\Microsoft IntelliPoint 5.x\
3.. After it extracts, exit setup.
4.. Open Windows Explorer, go to C:\Program Files\Microsoft IntelliPoint 5.x\IPoint\SETUP, and find "oemsetup.exe"
5.. Download intellipoint.ini from our servers.
6.. Drag and drop intellipoint.ini over oemsetup.exe; wait about 1 or 2 minutes, maybe more for slower machines, because you should notice disk i/o during this silent install, then go to CP - Mouse and have a little look see.. It should be installed
7.. Enjoy!
8.. If after these steps some functionality is missing, see this forum topic on hard-coding the device ID.
