<div class="markdown_content"><p>Hi all,</p> <p>I'm trying to open a V 1.56.49.0 Project on Codesys V3.5 SP17 Patch 2 and I get the following message:<br/> "The project has been saved with V1.56 and contains data which cannot be loaded with this version. As option I can just choose between "Download and setup a new installation" or "Continue with this version".<br/> If I choose the former the program crash, if a choose the latter I can access the project just in read-only.</p> <p>How can I fix this?</p> <p><img src="./attachment/CodesysErrorMessage.PNG" width="50%"/><br/> Thanks in advance,<br/> Kind regards,<br/> Alessandro</p></div>
