I took a look at openssl.exe with Dependency Walker and saw more than just one ordinal missing. I also took a look at the 3.0.6 box that was working and tried to find the difference. It is simple: the symlink of the machine that works point to the PHP 7 directory.
To solve this problem you can either copy the two files SSLEAY32.DLL and LIBEAY32.DLL or simply choose to use PHP 7 by left-clickin
