Had to reinstall lion operating system on mac and now will need to reinstall ms office; is the license tied to the computer or the number of times you reinstall. I do have a license left, but don't want it to be used on the same computer.
It's tied to the computer. It keeps track of the hard disk, Video card and motherboard on IBM PCs it should be the same on Macs. On your Mac none of this should have changed. So it should be fine with your re-install.
