Peter,
- FBA DLL/OCX Registration resource
- FBA Generic command invoking regsvr32.exe (included in the image) with your dll/ocx as an argument (also add /s switch)
- Register the DLL on XP Pro machine, grab all the registry entries (Regmon/Inctrl5/Regsnap/Regedit) and import using CD
- manually create all the reg.entries (painful, though)
