Important: This website is now read only (except to admins) to comply with the UK Online Safety Act. Composr CMS is in the process of migrating to a new Constitutional governance model and Bazaar development model, with functionality of the old website (constructed by ocProducts Ltd, the prior copyright holder, a UK company) spread between GitLab and the new website (which has no connections to the UK).
This is a Microsoft Web Platform Installer package of Composr. We will update this routinely when we release new versions, and update Microsoft with the the details.
It can be manually installed into IIS running the Web Deploy Tool, but it should soon be featured in the Web App Gallery directly. Therefore accessing this archive directly is probably of no direct use to you. If you do want to install on IIS manually, the regular Composr installers can do it fine.
