Hi, Platform: Windows Server 2008 Standard SP1 x64. DAX 2009 Client. Problem description: By clicking F1 or by choosing any information with an exception for “Enterprise Portal Administration” nothing happens. 1. After many desperate tries, it was decided to copy Help files (…\50\Client\Bin\Help\EN-US) from the working environment (OS: Windows Server 2003 x32). 2. Help file started to open but the problem with its reflection appeared (the Internet Explorer parameters were changed and “Initialize and script ActiveX controls not marked as safe for scripting” option was activated. 3. Help file can be opened now with an exception for leftside menu (there is no reaction when clicked on the link). Notes: When opening .chm files located in Axapta (…\50\Client\Bin\Help\EN-US) they work properly. Are there any ideas?
