1. Open Win32 OpenSSL Installation Project page.
2. Download the latest "light" Win32 or Win64 installation package, for example "Win32 OpenSSL v0.9.8l Light".
3. Install it to any location. Ignore "Microsoft Visual C++ 2008 Redistributables" warning (click OK) and select copying OpenSSL DLLs to "The OpenSSL binaries (bin) directory".
4. Copy libeay32.dll and ssleay32.dll from the bin folder to the same place where your QtNetwork4.dll or QtNetworkd4.dll is located.
