I have a Retail Copy Of Office, and I replaced my existing PC. Can I install my copy of Office on my new replacement PC?
Yes. As long as Office was completely and entirely removed from the old PC, you can install your Office on your replacement computer.
I bought a Retail Copy of Office and installed it on my PC. Can I install it on my laptop, too?
Yes. You can install Office on your laptop as long as you are the exclusive user of the laptop. This means that you can install it on your laptop, but not your wife's laptop. It is important to understand that the EULA allows you to install the second copy of Office on a portable device like a laptop, not just some any other PC. In summary, you can install a retail copy on your desktop PC and your laptop. It does not mean that you can install it on two desktop PCs. You don't have the right to install it on two PCs. You have the right to install it on one desktop PC and one of your own laptops. Any other combination is not allowed.
