Thanks, I´ll follow your instructions ....

Thank you very much

I think you need to

• Remove IPP from your computer and reinstall it (IPP 2018 update 1 works for me with VS2017) again. But when you are installing the IPP, make sure that the IPP integrates with your VS2017. You can see that on installation process, the installer says something like "integrating with Visual Studio 2017". If the IPP installer says "couldn't find Visual Studio", you will need uninstall VS2017 and install again too. When uninstalling VS2017, make sure that you removed all of the components and clean your computer from old VS versions.
• You need to rebuild the latest HISE with IPP yes (with your latest integrated IPP)
• And then try to recompile your project.

This procedure worked for me.

NOT: If you have older visual studio versions, I suggest that uninstall them, because it can give this error because of that too.

Hi, remarkablex

What I mean is HISE cant compile my proyect, when I set to "yes" the use IPP option in compiler settings.
I compiled Hise myself:
( version:1.5.1,
build time :6/03/2018 )

and I´m using Visual Studio 2017.

When I try to compile my project( with IPP) cmd.exe say me :

Apparently, as you can see, compiler can´t find "ipp.h"....
