<div class="markdown_content"><p>Hello!</p> <p>I use Codesys v3.5.15.50. I got the error: <br/> "<span>[ERROR]</span> visu utils, 3.5.17.0 (system): Library Manager <span>[Device: PLC Logic: Application]</span>: C0521: The library "visu utils, 3.5.17.0 (system)" was created with the unknown compiler version "3.5.16.0". "</p> <p>I'd like to downgrade "visu utils" library version to version - 3.5.15, but I can't find the way to do it.</p> <p>When I try to find the library Codesys only shows the latest version - 3.5.17.<br/> With "Edit Repository Location" dialog I have only the local repository available.</p> <p>Could you provide me, please, the link to the remote Codesys repository, <br/> where can I find previous versions of libraries?</p> <p>I was searching a lot in Online Help and in FAQ and I can't find this link.<br/> Why the process of work with different versions of libraries isn't clearly described in the documentation?</p></div>
