Hello, the steps are, download the SDK, unzip the SDK, search for the example that you need to review, on the root C:\Users\mcuxpresso\01\SDKPackages\SDK_2_3_0_EVK-MIMXRT1050\boards\evkmimxrt1050
Then when you open the example on the IAR the IDE automatically will ask you to install the DSP and DFP click yes.
Best regards,
Pavel
