I am reusing the projucer just adde an exporter for visual studio 2017 .
What should I do here ?
I am opening the projucer from inside the folder with the plugin source.
I downloaded JUCE from the website windows link just now and just opened it up.
Does it need to be compiled I dont think so the demo projects build when clicked on inside the JUCE folder which I stuck on my desktop.
Thanks for you help. Sean

Download and install Visual Studio. The Community edition is free.

The Projucer does not create Visual Studio Code configurations.
Although the names of these IDEs are very much alike, they are different tools.

Thanks sorry I am using Visual Studio my headline was misleading

First question, why aren you using such an old version of VisualStudio?

Oh that’s a good question actually let me upgrade it and see !

Same error in a different looking GUI sadly.

This is the more of the output from Visual stufio 2022
I hope it’s appropriate to paste all this.
Tons of warnings but no errros until the very end it seems. I am mystified.
I wonder if all the includes are being found ?

Is it this error crashing the build ?

Bingo ! this was the error unique to the windows compiler

I had to change

isnan(integer) call with isnan(static_cast<double>(integer)).

Glad you got it figured out. Also good that you upgraded to latest VS. I assume you have a call to fpclassify, or some other library that you are using calls it?

10 
### XCODE C++ compiler this passed ok 
#include <math.h>
if (midi_note_number > 0 && !(isnan(midi_note_number)))
        {
            m_mod_g = m_mod_g + 1 / midi_note_number;
        };

## compiler in visual studio wanted this 
if (midi_note_number > 0 && !(isnan(static_cast<double>(midi_note_number))))
        {
            m_mod_g = m_mod_g + 1 / midi_note_number;
        };

I believe underneath the math library is the fpclassify which didnt like having an int passed to it in that compiler.

Thanks for you great help and patience.
Sean
