Interface Error: Dual Interface Update: Not a member

I updated an interface of an ActiveX control with two methods. I compiled the .idl file and generated the ocx. The interface had 89 methods. I got the following warning which I ignored:

warning MIDL2362: too many methods in the interface, requires Windows NT 4.0 SP3 or greater

I am compiling on WinXP with SP3 installed, using VC++ 10.0 compiler. Hence, going by Microsoft Documentation, there should have been no warnings.

I updated the client application with a call to these two methods. I compiled the client and verified that additional methods have been updated in the .tli and .tlh files. However, when the methods are invoked, I am getting OLE error 'Not a member'.

I debugged and found that the dispatch table does not have an entry for additional methods. How do I resolve this issue?

Thank you.
