KO GmbH provides a highly experimental MSI installer for the Calligra Suite on Windows for testing. Currently, Words, Stage and Sheets, Flow, Braindump, Karbon and Krita are included in the package.
Please note that these packages are not yet suitable for daily use. They are meant as a proof-of-concept of work in progress. The installer as well as the software will be refined before the project is over. If you have any problems with the installer, please contact us on irc: #calligra on irc.freenode.org.
