Your registry is indicating you installed the software in D:\visual_studio_15 but the compiler executable D:\visual_studio_15\VC\bin\cl.exe is not being found. Could you check to see what is under the D:\visual_studio_15 directory? Is it possible that you installed there but moved the files afterwards?

I had a similar issue, and from what Walter Roberson said:

Find out there your visual studio is installed. If it is not 'D:\visual_studio_15\' then

Run --> Regedit Navigate to: HKLM\SOFTWARE\Microsoft\VisualStudio\SxS\VS7 (HKLM = HK_LOCAL_MACHINE)

And manual edit the registry to where it is
