We have this pretty extensive vb6 windows application which uses ArcObjects to deal with SDE data. It also uses Mapcontrol.ocx and PageLayoutControl.ocx to display spatial data. Now we are planning to upgrade from 9.3 to 10 and we dont have time to convert this vb6 app to .NET right now so just want to make it work with 10 first then doing the conversion.

I have a test machine which has ArcGIS 10 loaded with valid ArcInfo license. When I opened up the vb6 project of course it failed to load the 2 ocx controls. I tried to use the add components dialog to add the MapControl.ocx from C:\Program Files\ArcGIS\Desktop10.0\Bin directory but it failed to load, saying "Error in loading DLL". If I try to use ESRI Controls 10.0 it says I dont have ArcGIS Engine license which I dont have and it's not required in 9.3.

Has anyone had similar issue? We really dont time to rewrite the whole in .NET before the upgrade.
Thanks in advance.
