I have also installed the Windows Live Essentials 2011 (with Messenger, Mail, ...). What's the problem?
I installed Windows Live Essentials 2011 on 7955, latest build using the offline installer, works great...
I installed all components of Windows Live Essentials 2011 on 7989, using the latest offline installer, works great... and live mesh works lovely!
I get an error 0x80040800 says I have to reboot but no matter how many times I reboot it will not install.
