Is it possible to inject 64 bit dll into 64 bit host app from 32 bit app in native c?

I compiled the dll I want to inject in both 32 and 64 form, but when I call
I get WOW error.

The host application must be 64-bit in this case, you could probably implement a 64-bit application to run in the middle but it would be easier just to do a 64-bit build of your native app.

Obviously a .NET app doesn't have this problem if built for AnyCPU, although since VS2012 the default behaviour of AnyCPU is now to "prefer 32-bit" - there is a setting somewhere for that in the project properties.

Thanks. I couldn't build it in 64-bit, because of some libraries, so I implemented a 64-bit helper app.
