on WinXP and Win2003 Server one now has the possiblity of not beeing forced to register COM Dll's in the registry .. one now can provide a manifest XML file with the registration data and place it into the application directory ..
I will have to document this up in the Help File. I have in the past done testing the OCX not being registered and having it in the same folder as the application and on some OS's without a Manifest, I was able to get it to work.
