uVision5 Pack installer and include paths

Just trying to get to grips with some code that's landed on my desk. It's for STM32F103RB and I have uVision 5. I've got the pack installer to add the right device packs but when building the .h files are not being found.

Doesn't the pack installer set up the include paths correctly?

What's not helping is that the code was probably developed with some older version of the ST peripheral libraries and these are not included in the source files I've been given...
