C ++ / CLI 64-bit COM

I have a C ++ / CLI assembly that wraps a native 32-bit dll.

The assembly is used both from .Net and for COM (office).

Now I have a client that runs a 64-bit office.

Is it possible to create a C ++ / CLI assembly that uses a native 32-bit DLL and exports a 64-bit COM interface?

No, you cannot mix code with different bit precision in the same process on Windows. You need to force 32-bit code into a separate process or convert this DLL.
