I have achieved to pass this error by copying msvcr120.dll and msvcp120.dll in to bin folder of openssl
But now I receive new errors
QSslSocket: cannot call unresolved function SSLv3_client_method
QSslSocket: cannot call unresolved function SSL_CTX_new
QSslSocket: cannot call unresolved function SSL_library_init
QSslSocket: cannot call unresolved function ERR_get_error

I have the test line of code in qt
qsslsocket::supportsssl()
that returns false

In my .pro file I have the qt+=network and I have also paste to qt bin folder the following dlls
libeay32.dll
libssl32.dll
ssleay32.dll

Any idea about that?
