Manifest OCX?

Hello. I'm trying to manifest an OCX, so that its forms are displayed manifested, regardless of whether the client program is manifested or not.

I found that I need to do two things:

1) Add the manifest with resource ID ISOLATIONAWARE_MANIFEST_RESOURCE_ID RT_MANIFEST (value 2 instead of 1)

I already did that.

2) Compile with:/D ISOLATION_AWARE_ENABLED

The value of that flag is 1. But where am I supposed to do that?
