not sure if i would run with that one. i believe they have upped their key logging. plus if caught they can come after you since its not a registered copy and illegal. however openoffice has most of the same apps as office and is free.
Are you trying to install office software that came with another machine?. If this is the case it will never install because the product you have is an OEM which means the license works only on that machine and not on all machines. The license dies with the machine.
