Qt Installer Framework and OpenSSL

[ExorcistInc]

Hi!

I am creation simple app online installer with Qt Installer Framework 2.0.0 on Windows 8.1
binarycreator gives me this error:

Could not register file downloader for https protocol: QSslSocket::supportsSsl()
 returns false

But it creates installer and it works if Repository Url in config.xml is something like http://localhost/repository

But if repository is hosted with Dropbox or Google Drive, installer stops with this error:

How to fix this?

PS Google Drive link to repository, if necessary:

I figured out, that QSslSocket::supportsSsl() returns false due to lack of the OpenSSL installation.
Adding OpenSSL dlls to the installer dir solved this problem and starts another:
How to distribute the installer, which depends on OpenSSL dlls?
