“From PDF” toolset not available in 10.3

I’m running ArcMap 10.3 and there is no “From PDF” toolset available in my conversion tools list. Also, trying to use the ArcPy PDFToTIFF_conversion method fails.

Specifically ArcMap is version 10.3.0.4284

Python is version 2.7.8 (downloaded & installed from my esri portal)

I think my version upgrades on this machine have gone from 10.1 > 10.2.2 > 10.3. I do not have ArcGIS Pro installed, just ArcMap 10.3 Basic.

Am I missing something, does anyone have any idea on what to check or look for?

Edit: found the install folder and it looks like I might be running 10.3 prerelease. I am going to reinstall 10.3 and see what happens.
