Is it possible to load x64 dynamic library in x86 application?

Question

C++ / C#

I have a plus program. It is compiled for x86. Sometimes you need to connect the x64 library to it. But I get an architecture compatibility error.
Is it possible to shove code into the program that will be executed when it needs to work with x64?

Answer 1

Not allowed. Only collect a separate executable and connect to the main one through the spherical memory.

Answer 2

You can add this code. The code that will launch the intermediary that will download the library for you.
