Without the code about all I can do is guess. Does the standalone program work on your computer but not others' computers? Are you sure the file is being created? Can you delete if prior to running and make sure it's actually creating it? Because the deployed program will, if you don't specify the complete path and just use the current folder, use a different folder than the development environment, so I want to make sure you're not looking at a file created while you were in the development environment. Are you using fullfile() to specify the full path of the file? If not, you definitely SHOULD be. That could be the cause of the problem? You aren't trying to put it in a protected folder, like c:\program files, are you?
