title: How to create excel add-in (excel 2003 or previous version) package with activeX dll?
body: <p>I am new to excel add-in prgramming and I am having a existing excel add-in project need to modify.</p>
  
  <p>The plug-in has 2 parts, one is programmed in VB and compiled into a ActiveX DLL file, the other part is inside the excel as an add-in.</p>
  
  <p>I already modified the source code of the DLL and recompiled a new DLL, but I don't know what is the correct way to re-package the 2 parts into one excel add-in package and give to my colleagues.</p>
  
  <p>I tried to remove the reference to old DLL from excel, but it seems I could not do that, it will always be there and I can't really remove it.</p>
  
  <p>This add-in is for excel 2003 or previous version, not for excel 2007.</p>
  
  <p>thanks a lot for your help!</p>
