the question using IS12

[alunlee]

I was confused by the following problem: I have written an application for a serial communication project. My app used the mscomm control to finish the task. At last, I launched the IS12 and created a installscript project. With the help document of IS12, the setup package was build successfully. The setup can install my app. But those PC without the development environment could not run the app successfully. The main reason may be that the registering of the mscomm control failed. Does this control have another dependencies or I have missed some additional configuration?

It sounds like your end users must purchase a license to use mscomm: http://support.microsoft.com/kb/315501

You might want to modify the code to use the Windows API or preferably the SerialPort class in .NET 2.0 rather than using mscomm.
