This software and drivers are still in a beta phase but are necessary for your Microsoft input devices to work properly under Windows 7.
The download and installation process can take up to 30 minutes so you should schedule accordingly.
IMPORTANT Always install the software using the Setup program instead of installing the drivers directly. This download and installation process will take approximately 30 minutes to complete and you will not be prompted for an action for several minutes. Do not click "Install" more than once.
Microsoft is not aware of any issues for Windows 7 and LifeChat.
