question?why it is asked to install such way?
The current version has to install some components to allow it to run, to put it simple.If you don't trust it, there's a virus total link on the download page that you're free to look at! In the next update this issue will also no longer exist.
when cumflation and ntr in seetings will be available?
The first will be available in the next update, the latter is renamed a little but still not available unfortunately.
