If you try to convert a project to knxproj format and you receive one of the following errors, then please look for the error message and its solution below:
Error: This request operation sent to ..... did not receive a reply within the configured timeout (00:01:00)
You may extend the timeout by editing the file ProjectFileExporter.exe.config, which is located in 'C:\Program Files (x86)\ETS ProjectExporter' using e.g. notepad. The relevant line is
<projectExporter sendTimeout="60" receiveTimeout="600" />
Try changing the two timeouts to higher values (the times are in seconds).
