Thank you for the post. If you are referring to the CT desktop adapter (as shown in your screenshot), this model has already built-in driver provided by Microsoft*, thus you can see it is installed already in your Windows* 2012 R2 system, However, we do not have the PROSet software for this adapter under Windows 2012 R2, thus when you try installing Intel PROSet software, it is not supported. You may refer to below link for reference.

Hope this clarifies.
