I have the same problem as in this link Open SSL not found - Questions & Answers - Unity Discussions
I am Using Unity 5.1.1f Professional on Windows 7 - 64 and the latest Facebook SDK 6.2.2
Facebook interface works when I am not on Android Platform. When I switch to Android for which I do not have a pro licence I encounter the above problem.
I have done these steps
- Download and install OpenSSL. Win32/Win64 OpenSSL Installer for Windows - Shining Light Productions
Win64 OpenSSL v#.#.# (not Light) - Added the OpenSSL/bin directory to my path.
“;C:\Program Files\OpenSSL-Win64\bin” to the end of the value text.
Restart Unity3D.
When I open Unity again I can edit everything else but when I go to Facebook/Edit Settings, Unity stops responding.
I have also added the JDK (Java Development Kit) bin directory to the Path variable value and still the same unresponsive problem?
Any help would be appreciated
