Answer

This is a permission problem. although you may belong to the administrator group you may have to acquire permission to run things. if you have windox home edition then you will have reboot in safe mode and login as the adminstrator. then use my computer to access folders and right click a folder and select properties and then security. check who the owner of the folder is and add yourself to this group.
