Multiple ActiveX Controls at once?

I have an ActiveX Control on a HTML page that is processing information between the client and a server. If it detects something missing, it attempts to punch a new object tag into the HTML page using DHTML. The reason is to utilize an existing ActiveX Control instead of incorporating the existing code into a new Control.
The DHTML is added to the existing page because the Download Component Manager fires and prompts the user to load the ActiveX Control, if it is not there. The problem is that after answering YES to the download security message, nothing happens. The ActiveX Control is not loaded on the system (Downloaded Program Files or Object Viewer in IE) and there is no CabDownloadError file in Temporary Internet Files.
Can a secondary ActiveX Control be loaded while a primary ActiveX Control is running? The second Control never runs because it is never loaded on the client machine.
