The Windows installer for Groovy 2.5.7 is now available from Bintray: https://bintray.com/groovy/Distributions/Windows-Installer/groovy-2.5.7-installer .
The Windows installer for Groovy 3.0.0-beta-1 is now available from Bintray: https://bintray.com/groovy/Distributions/download_file?file_path=groovy-3.0.0-beta-1-installer.exe . These are also the first releases where I've published a preview of Windows Installers created with the WiX Toolset. I invite you to try them out and provide any feedback you might have. It's my intention to eventually replace the current NSIS-based installer with this installer. I believe it to be reasonably stable. I've personally been using these instead of the NSIS based installer for a while now. Here are the links to those installers: 3.0.0-beta-1: https://bintray.com/groovy/Distributions/download_file?file_path=groovy-3.0.0-beta-1+%28preview+installer%29.msi 2.5.7: https://bintray.com/groovy/Distributions/download_file?file_path=groovy-2.5.7+%28preview+installer%29.msi Be aware that you need to fully uninstall the NSIS based Groovy installation before installing with an MSI installer. -Keegan
