Hello everyone: I'll be highly appreciated if anyone of you can help me to clarify the following error message which have bothered me for the past two weeks. User command #2 E:\work\copy_bin.bat --- User Command terminated, Exit-Code = 4 ".\obj\product" - 1 Error(s), 140 Warning(s) The builded binary file is working properly. I just want to know the root cause of this kind of error message. I do have a file named copy_bin.bat, but it is empty and I could find from which method or file it is called. Thanks. Eric
