@nesta99 i would do it next week on another pc i have. my procedure was like the rest. i went to the intel ipp site. I downloaded the toolbox offline, I installed all the components. then i downloaded visual studio. I launched a first compilation which failed because I had not installed the visual studio module (when you get an error it will tell you to download the modul x3737838388 for example). once you know the right module you go back to the visual studio installation and check the box corresponding to the module. then you relaunch your compilation and it works. concerning ipp I have the latest version because I downloaded it a few weeks ago
