<div class="markdown_content"><p>Yes. So if I install in the same directory I have only one Gateway and CODESYS Control Win V3 (The latest).</p> <p>But what if I install in separate directorys and want only the latest Gateway and Control Win do I have to uninstall these packages from the old installation? I am thinking that it slows up the computer if I have several of these in my taskbar.</p> <p>Is there a need to have a old version installed or does the development enviroment work just as the old if i install old libraries and choose to Fix the compiler version to the old one for the old projects?</p></div>

<div class="markdown_content"><p>What is the recommended way to update the Codesys Development enviroment?<br/> If I just install a new version i get several versions on my computer.</p> <p>So should I uninstall the old one first or is there another way?</p></div>
