<div class="markdown_content"><p>I have had this happen many times in many CoDeSys versions.</p> <p>Here are the steps I believe you can use to recreate it.</p> <ol> <li> <p>Keep CoDeSys application closed.</p> </li> <li> <p>Open a help file *.chm from a CD. Windows will use it's default reader. I was looking at help files for other PLC manufacturers on a target CD.</p> </li> <li> <p>Remove the CD from the drive.</p> </li> <li> <p>Open CoDeSys and go to the help menu or press F1.</p> </li> <li> <p>You will get the following screen capture but you can not get rid of the message box. You are stuck. Pressing any button will not close the message box.</p> </li> <li> <p>If you put the CD back in you can then move on. Not sure if you can use any CD or the one you used to view the other help files. I used the one I opened before.</p> </li> </ol> <p><img alt="IMG: CoDeSys_Help_Error.JPG" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=176"/></p></div>
