If you did not buy it online, you are out of luck. You will have to buy 2010:
Buying Office 2010: Summary
When you buy, it is my personal preference to insist on the "FPP" or Retail license for home and small business. It gives you the best set of user rights
of the license. It allows you to install on 2 or 3 machines at the same time and to transfer the installation when you want to. The "PKC" or Product Key Card is slightly cheaper, but allows installation on only 1 machine and no transfer rights. If your brand
new computer "melts down" in the warantee period, it will be replaced, but you will have to BUY another PKC license!
Note:
no matter how you buy Office you need to keep "physical" copies of 3 pieces of information. The purchase receipt (credit card statement), Product Key, and the installation file on CD/DVD. With the first 2 you can get replacment copies from MS, with the
last 2 you can re-install at your convienece without talking to MS (ie 5 years down the line when you retire this machine and get a new one).
When buying Office 2010 you have to make 3 decisions:

(Full or Product Key Card license)
-What type of installation you want (“normal”

Here is more info about those decisions:
Product Key Card vs “Traditional” Retail disk -
http://www.microsoft.com/oem/en/products/office/Pages/office\_2010\_sell.aspx
“Medialess” Installations: Product Key Cards PKC (2010) / OEM / MLK(2007):
·For
use on new, preloaded PCs only
·1 license
/ 1 device / non-transferable
·Activates
preloaded Office or Downloaded installation files
·Does
not include media
Microsoft® Office 2010 Product Key Cards contains a 27 char “PIN” which you have to enter at this site:
https://office.getmicrosoftkey.com/ to retrieve your 25 char product key. This key will activate Office on only one PC. No disc supplied. The PKC license is not transferable
to another PC. Next week if your cat uses your computer as a litter box, you have to BUY A NEW PKC.
Take a look in the Help screen for the PRODUCT ID. OEM activated Product ID’s will include the letters “OEM”.
Retail Box with CD: FPP:
·Home
and Student: 1 license, up to 3 concurrent devices
·Home
and Business and Professional: 1 license, up to 2 concurrent devices
·License
is transferable to another PC or Owner
·Includes
installation file on CD for backup
This license type, often referred to as Full Packaged Product (FPP) in the past, includes a DVD, a 25-character Product Key, and a Quick Start Guide. The 25-character
Product Key will activate an Office 2010 preloaded PC. The DVD may also be used to install Office on another. The number of installations (2 or 3) and users (1 or 3) depends on the specific Office suite purchased.
A Traditional Disc product license can be transferred to a different PC if the user upgrades to a new PC or if the owner wants to sell it to someone else.
OEM PreInstallation Kit - OPK:
If you do not explicitly order a vendor installed copy of Office, the manufacturer will use the MS provided “Single Image” installation file to install trial versions
of: Office Home and Student, Home and Business and Pro. The user has to separately purchase a FPP or PKC Product Key for the Office version they wish to keep.
Click to Run (CTR) Information
MS will automatically give you CTR if it detects a High speed internet connection. My personal preference is to avoid CTR for home use. You have to look carefully
on the page for the 'advanced' link to get the "normal" installation file.
Go to the MS Office site
http://office.microsoft.com/en-us/ and search for “click to run” you will see titles such as

Office Discount Deals
There are 2 ways you can get an even better deal on Office. The “Academic” discount for college/university students and the “Home Use Program” for corporate
employees.
HUP, Home Use Program
The Home Use Program is a deal where companies with a site or volume license activate part of that license agreement that allows their employees to get a
copy of Office to use at home. The HUP is the best discount you can get.
https://www.microsofthup.com/hupus/contactus.aspx---click
on Customer Support and then Contact Us.
Corporate HUP admin can download from here for employee without email address.
Employees with corporate email address and the corporate “Program Code” can also download from here.
Academic
The Academic discount is the next best Office deal you will find. For students who can prove they are at MS approved educational institutions can buy Office
Pro for $100. Be sure to get the installation disk at the same time, even if you have to pay $10-15 extra.
