Intel Fortran compiler not found

I'm trying to get Fortran mex file compilation working on Windows 10 in Matlab R2019a. I've got a trial version of Intel Parallel Studio XE 2019 installed and Microsoft Visual Studio 2017 Community Edition installed. When I try mex -v -setup FORTRAN I get an error:

>> mex -v -setup FORTRAN
Verbose mode is on.

Error using mex
No supported compiler was found. For options, visit https://www.mathworks.com/support/compilers.

Visual Studio apparently was a 30 day trial rather than a full installation (it's expired now and will launch and function for a short time before a popup freezes the program and asks me to buy a license or exit Visual Studio), so that may have something to do with this error. Looking at the output, it looks like it finds the IFORT_COMPILER19 environment variable, the ifort executable, and a registry setting, but it fails on a command to echo the vcroot environment variable. The problem seems to be that C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build doesn't exist; everything up to "Build" does, but Auxiliary only contains a folder called VS for me. Is there a way to get around this?

Update: I got a copy of Visual Studio 2017 Professional through my company. However, even with a valid, active Visual Studio installation, I'm getting this error. Is there a Visual Studio component that needs to be installed?

Hi Josh,

Did you manage to solve your error in the end? I am having the same issue of Matlab not able to find the parallel studio fortran compiler.

It seems you should make sure the c++ part has been installed when you install the Visual Studio such that matlab can detect ifort. Just notice the panel after installation of VS, it will inform you what component has not been installed and also the accompany impact.
