QCA - RSA not supported on Windows without Qt

[TheQuake]

I can run my project without any issues on my pc, rsa works well, it's working also outside Qt with required dll's.
I tried to run my project on next pc without qt or openssl installed. I copied all required dll's, and .. RSA is not supported. I installed OpenSSL libraries on this pc like on mine, it changed nothing.
I added
qApp->addLibraryPath(qApp->applicationDirPath() + "/plugins");
Then i copied crypto directory to "plugins" - still rsa is not supported.
Current tree list of directory:

³ app.exe

Hi. Welcome to DevNet.
What compiler do you use?
Try install vcredist.

Thanks, i'm using MinGW 4.8.2 with Qt 5.3.1. I installed vcredist (2008, 2010, 2012) - without effect.
On my own pc i have installed qca in qt directory, so i just adding CONFIG += crypto to get qca available in my project.

I tried QCA::pluginDiagnosticTest, results are:
on my pc:

Tried as administrator, on both machines they are same libs

Hi,

Have a look at the dll's with dependency walker to see if you're missing something.

Hope it helps

And probably "The Windows Deployment Tool (windeployqt)":http://qt-project.org/doc/qt-5/windows-deployment.html could help you.

The Windows Deployment Tool just copied same files like i have copied. Still not working on another machine.

@Found metadata in lib C:/Users/Administrator/Desktop/appa/plugins/

trator/Desktop/appa/plugins/crypto/libqca-ossl.dll: "@

Is there any way to check/debug more information about loading plugin?

Uhm, the problem was other version of openssl on my pc and another.
Thanks all for answers :)
