Just to close the loop on this for those on CD, the missing .dll issue was diagnosed and resolved over in the ni.com/first board. Current workaround is to download the missing file manually, hopefully a corrected update including the missing .dll will be posted in a few days.
The thread discussing the issue is at:

The missing file (nicyapi.dll) and instructions are at:
