I found a solution by searching the internet.

The OS for my computer is Windows Vista 64bit Home Premium.

Here is the solution from internet:

Install Vista Service pack 2 ---- > http://www.microsoft.com/en-us/download/details.aspx?id=17669 [microsoft.com] (This is for vista-64bit) 

Run DXsetup in the Origin\ Plants vs Zombies Garden Warfare \__Installer\directx\redist\DXsetup.exe

Then Install DX 11 -----> http://www.microsoft.com/en-us/download/details.aspx?id=4390 [microsoft.com] (64bit)

Restart.

However, now I have a new error when clicking the "Play" button in Origin client:

“nvidia geforce 9300ge gpu does not support directx 10.0 which is required”.

Any suggestions?
