openssl 'ml64' is not recognized as an internal or external command

Question

I'm a newbie on openssl and I'm struggling to install openssl on Windows 7 64bits system. I've a trouble on 'ml64'. As I mentioned on the title, It just pops up on a command line that 'ml64' is not recognized as an internal or external command.

First, I installed Visual studio community 2015 but there were no 'nmake' and 'ml64' so I've downloaded visual studio 2010 professional. It has 'nmake' and 'ml64'. So I add these to system path. It still doesn't work though. ['ml64' is not recognized as an internal or external command] this problem still occures.

I have totally no idea what I have to do. Any suggestions?

Answer 1

in "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Visual Studio 2015\Visual Studio Tools\Windows Desktop Command Prompts", use "VS2015 x64 Native Tools Command Prompt" to launch your command prompts.

and you will find ml64 is available.
