Problem running Fortran compiler

[ivf_ian]

I am having problems running Fortran on Visual Studio platform.  I had been running my code successfully until recently when I received an objection that it couldn’t find a couple of ddl files.  I then installed VS, Base Toolkit, HPC Toolkit in that order and have now other problems.  See drop boxes, showing (1) cannot open include file string_h when trying to open a resource file and (2) warning about data type not matching when trying to compile a file.  I believe I was using ifort compiler before when things were running well, but now I suspect it is ifx.  I really don’t care which one is being used as long as the compiler works.  Appreciate any assistance with this problem

I had found the directory with the string.h file and inserted it into the resource folder additional include directories.  I should have mentioned that the resource appeared to compile OK.  So hopefully the string.h and handle issues are now resolved.  Thanks everyone for their contributions.  I have, however, found more hiccups and will start another forum request.
