No starting Microsoft Office Starter 2010

On 3/31/2014, I have purchased refurbished S3-391-6448 from walmart store, which must include "Microsoft Office Starter 2010".

This one;

This is a great one, but there is one poblem about office starter.

When I click microsoft office icon in start menu, "use" buttom does not appear on the pop-up. So, I cannot begin office starter version.

Instead, three selective icons make appear; "activate", "purchase", or "Try", like this;

Clicking "Try" leads to the page of temporary use for office 365. Clicking "Purchase" also leads to the web page. "Activate" requires the product key of some kind of office 2010 other than the Starter model.

My states is here

1. I confirmed user's guide, but there was no part of microsoft office.

2. When I intend to open the .docs, or .xlsx files, the same pop-up appers, which shows "activate", "purchase", or "Try".

3. There is no row including "office starter" in my installed program list.

4. There is a row including "Microsoft office 2010" in the list, instead.

5. After I deleted "Microsoft office 2010", the pop-up never appear. And no related program goes existing. 

6. There is "no" folder of C:\ProgramData\Microsoft\OEMOffice14\OStarter.

7. There is one folder of C:\ProgramData\Microsoft\OEMOffice14\Office14, which shows office other than starter ver, and occupy 1.3GB. 

8. Ocuppied space in C\program files(x86)\Microsoft office is about 6MB.

9. I have done Acer's factory recovery, but the problem remains in spite of initiallized. 

10. I have inquired to walmart, but they don't provide helpful informaion about software.

If the pop-up would be like below, I could begin the installation and use Office Starter 2010!

What should I do? Is there any method of starting office? Help me...
