Sorry to be so persistant but I am getting desperate.
I start a new blank project in vs 2017 and add nothing of my own.It gives error message " cannot open source file ctype.h".
This of course is followed by many more errors.
This is a NEW project and surely should work out of the box?
I tried googling for answer but answers were dated.
target is set to 10.015063.0 but retarget shows another number.,, other than that I see nothing wrong.
