Cannot push existing WES7 images to thin clients in Package Distribution Wizard

Hello,

I'm fairly new to using Dell WDM.

We have existing Dell Wyse 5020 thin clients running WES7.  A number of images and packages were setup for these and I can still deploy fine to these devices.  These appear in WDM as 'Windows Embedded Standard 7' OS.

We recently got a new shipment of Dell Wyse 5020 thin clients.  I have tested one and it is being discovered by WDM and I am able to right click and launch the 'Package Distribution Wizard' but none of the existing WES7 images are coming up.  The OS for these new thin clients is coming up as 'Windows Embedded Standard 7 P'.  Could this be why?  Or should I be able to use the same image as I did for the existing thin clients because they are all still WES7.  Is there another step I need to do to make the images come up for these new thin clients or do I need to create a new image?

Thanks,

Cindy
