english.WelcomeLabel1=Welcome to the%n[name] Setup Wizard
english.WelcomeLabel2=This will install Node-RED on your computer.%n%nInitially we check the version of Node.js installed is %1 or greater. We will try to install node %2 if none is found. Optionally you can choose to install node %3.%n%nIf necessary we will then remove the old core of Node-RED, before then installing the latest version. You can also optionally specify the version required.%n%nWe will finally try to run 'npm rebuild' to refresh any extra nodes you have installed that may have a native binary component. While this normally works ok, you need to check that it succeeds for your combination of installed nodes.%n%nIt is recommended that you close all other applications before continuing.
WizardReady=Final verification
ReadyLabel1=We just ran a final verification of your installation setup.
