The Windows installer for Groovy 3.0.0-rc1 is now available from Bintray: https://bintray.com/groovy/Distributions/download_file?file_path=groovy-3.0.0-rc-1-installer.exe .
I've again included a preview of an msi built with WiX, which I'm seeking feedback on: https://bintray.com/groovy/Distributions/download_file?file_path=groovy-3.0.0-rc-1+%28preview+installer%29.msi . Be aware that you need to fully uninstall the NSIS based Groovy installation before installing with an MSI installer. -Keegan
