I can put files on Skydrive but when I put in an email address that I want to add for sharing I get a pop up saying Windows is unable to find the address. I have also tried to share using a Homegroup including sending my homegroup  ID Code to the person I wanted to share with and adding

their ID Code to mine but all to no avail. I have Windows 7 and the other operating system is Windows 8 on a  new computer. Any advice would be

much appreciated.
