Can you install Office 2007 Standard (non-academic) on 3 PC's?

[Pagoda]

I am looking to purchase Office 2007 Standard (non-academic) but I need to be
able to install it on 3 PCs that I work with between school home and work. I
am not sure if the suite allows you to install on 3 PCs or just 2. Usually
its just 2 however I cannot find anything online about getting a 3rd license
without having to buy another copy of the same software. So I was wondering
if someone knew the answer to this question, please help!

Two "devices", including one portable, according to License Agreement for
Retail purchases (fpp package.) OEM is for one device as is the downloaded
Media-less license kit.
http://office.microsoft.com/en-us/products/HA102103171033.aspx doesn't
specifically mention the Standard edition and I can't find anything either
specifically for this version of their suite. As far as I can tell,
therefore, it would be the same as any other retail (fpp on the package key
label) software.

You will have to purchase a second copy or get a license separately for the
third machine.
