Qt "Creating SSL context" error in few computers

I have this "Error cr开发者_如何学Goeating SSL context" in a C++ application based on Qt.

I've put these DLL in the application directory and in "C:\Windows\system32":

- libeay32.dll

- libssl32.dll

- ssleay32.dll

But still have the problem. It's weird because the application still works on allmost all the systems.

Idees?

All computers need to install the Microsoft Visual C++ 2008 SP1 Redistributable Package (Download here).
After installation, all works!
