Hi Rafael, Hi Henkac,
We are trying to investigate why the RSA help doesn't work for you.
We tested the Brazilian version of RSA 2016 and the help is working properly for us in all browsers.
We would like to find out where the problem is and your help is appreciated.
It may be a problem with the local region settings and redirection of the link, but we would like to verify it first.
Could you let us know what is happening exactly when you try to launch the help button from the Preferences dialog? Do you receive the Preferences topic in the browser?
If not, could you try to click the link below and let us know what you get in your browser and which browser you use?
