Questions about downloads
Where does the download come from?
Direct files are downloaded through NetCloud24. Installers come from the source addresses listed in the catalogue and are passed on unchanged. Links labelled as a publisher’s page open that website.
Does downloading include a software licence?
Downloading an installer and purchasing a licence are separate actions. Free software follows its publisher’s licence; commercial software may require activation or a subscription.
