I've installed Office from an MS Office CD on my desktop and laptop which constitutes two installs. I'm doing a full upgrade on my desktop including mobo & HD and I'm wondering if I'm going to have a problem installing Office on my new system. Surely MS must allow for system upgrades or HD replacement. This is for my home office PC and I don't want any unpleasant surprises when I try to install Office on my new build. Any input will be greatly appreciated. Thanks!!!
