Problems with applying drivers

Hi. 

I've had a struggling with applying drivers for a new machine model we started to use in our company. 

I've made a step in our task sequence to apply drivers, if the wmi query returns version "ThinkCentre E73".
When i try to run the wmi code on the computer after installtions, it says "ThinkCentre E73" 

So cant really see the reasons why its not installing the drivers.
Here is what the smstslog says about the step: *

Any ideas left? 
It's not bringing an error or anything, and my best guess would be that it doesnt respond to the version number. 
How can i troubleshoot ths further on? 

Thanks in advance
