Concept 2.6 is abandonware . Schneider Electric no longer sells licenses or provides technical support for it. If you own a legitimate hardware dongle (even if broken), using a portable emulator to access software you paid for is generally considered ethical and legally defensible. However, downloading a cracked portable version without ever owning a license violates copyright law.
In the world of industrial automation, legacy systems often pose a unique challenge. For facilities still running Modicon PLCs (Programmable Logic Controllers) from the Schneider Electric family, Concept is a name that commands respect.

Absolute Linux will continue development under eXybit Technologies, built with the same approach and
structure we've used to develop RefreshOS. We're not here to reinvent what made Absolute great, we're here
to carry it forward.
Since 2007, Absolute has stood for being simple, pre-configured, and lightweight. Slackware made easy.
That core philosophy isn't changing. Absolute will always be free, open-source, built for ease of use,
and based on the Slackware foundation.
As of now, there is no set release date for the first eXybit-developed stable version of Absolute Linux. We're bringing Absolute into modern computing while keeping it minimal. The first step is to preserve what already exists, rebuild the underlying infrastructure, and create a canary version of the next major stable release.
You can still download the original versions of Absolute Linux by Paul Sherman on SourceForge.
