Configuration tool for WIZ105SR

I am using WIZ105SR module and need to provide configuration tool to the customer. However I want to provide only limited functionality to the client. How can I modify the configuration tool source code which has been provided on the wiznet site.

Configuration Tool for WIZ100/105/110SR is developed by Visual Studio 6.
Install the Visual Studio 6 and than open the prjSEGConf.vbp file using Visual Basic 6.
