Most licenses allow you to do pretty much what you’ve described. You’re allowed to have Office installed on one computer at a time. You will need the original installation media that you used to install Office 2010 the first time.
I’ll walk you through it.
So, let’s assume that Office 2010 is on computer A and you want it on computer B. The steps are actually fairly simple. First, install Office on computer B using that original media.
You won’t uninstall Office from computer A just yet. You’ll see why in a moment.
Entering the product key
As part of that installation, you’ll have to enter the product key. That determines the ownership of the product.
If you don’t have the product key for your Office 2010 installation, you’ll need to use a program called Belarc Advisor on computer A.
Belarc actually does an inventory of programs on your computer, but it will also report the product keys for the versions of Office and even Windows that are on computer A. That way, you can grab the original Office 2010 product key.
Now, this is where things could get interesting. I really don’t know how complex the Microsoft Office activation really is. If it detects that you’re actually moving it to a new computer, they may have you call in. Typically, it’s an automated system, but don’t let it frighten you. Just do the activation.
Once you have things installed and activated on computer B, then run the uninstall program on computer A and you should be good to go.
