Qt "Creating SSL context" error in few computers

Question

I have this "Error creating 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?

Answer 1

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