How to bind two .exe files?

I have two .exe files and I want to bind them together. When I run the first file then I want the second file launched too. How can I do it manually?

According to the above image, How can I find the entry point and then jump?

Thank you.

Any idea? I’m thankful if anyone show me a solution.

Can I do it manually?
