Okay, as a workaround you could install OpenSSL on your computer.
Open up Terminal again and type the following things:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install openssl
After you type these things, open up the launcher again and let me know if it works.
You may need to link OpenSSL, but I don't think that you'll need to. If installing using just the two lines above does not work, type the following line into Terminal and try again:
brew link openssl --force
NOTE: each of these lines will take some time to do their thing. Just wait until they finish before typing the next line.
