Blueprint nativization always fails

Hello, I don’t have the error codes at the moment, but I am not able to nativize blueprints at all, this feature just doesn’t work for me.
I get something like libcurl error
I obviously have visual studio, both 2015 and 2017 installed, I have c++ installed, net Framework, I have everything. But it just won’t cook the content, I
​​can’t produce a build sitw my blueprints being nativized. Please suggest what could be the reason.

I tried both inclusive and exclusive methods.

Can you share the blueprints you suspect? Maybe try making a new project and one by one include Blueprints and Compile + Build in a modular fashion.
