I have created a com control implemented in dll. One application is using this control and my clients were using this application for last one year. Now I have introduce the functionality of drag and drop in this control and want to give this dll to my customer.Now I want to release new version of Dll so that my clients will get this functionality of my control.
Problem is that I want to release this new version but donot know how to do it. Whether I have to change the name of DLL or just change CLSID. On my local machine I have unregister the old dll but I can not unregister old dll which my client currently use. Please reply.
