I wouldn't upgrade to FM12 until reading the bugs listed in the last pages of the Known Bug List to see if any of the issues listed there will create significant problems for my user base.
You may need to create a small batch file with this command line and parameter and use send event to open the batch file instead of trying to launch the application directly via send event.
Thanks for the quick response. I don't see a difference between using a batch file or the application if the argument as a parameter specifier is included for either. In other words, if I use a batch file with an argument then why not simply run the application with an argument? It just occurred to me that maybe you mean to have FM programmatically create the batch file, which is an intriguing thought. The bottom line is that it sounds like the Send Event function cannot use arguments in the command line.
FM can create a batch file, use export field contents to export it and then use Send event to execute it. But that's not what I was suggesting.
This script step is not often used and I'm not sure that you can use it to send the parameter to the target of the send event succefully. I do know that you can use Send Event to execute a batch file so if you can get a command line to work for you, putting that command line in a batch file may work when send event does not. The key difference being that you are no longer sending any paramter to the target of your send event step.
