Why does self-written software not run on other computers or does it work incorrectly?

Question

C++ / C#

Hello, I have such a problem.
I wrote the software, it has two links, if it's important, to MySQL.Data and OpenQA.Selenium.
Everything works fine on the native PC, as it was intended, but if someone else starts it, the
software can start for 1 second and turn off or give an error "Program shutting down".
Tell me what I'm doing wrong. Visual Studio 2017 Language: C#.

Answer 1

No problem logs - you can only recommend a crystal ball. Does the application log its work? There can be tons of reasons, up to the fact that the machine on which the application is launched does not see the database server

Answer 2

Alternatively, not all dlls are bundled with the application

Answer 3

In general, windows has its own event log. All application crashes are written there. Including yours.
You can go there, the cause of the error is described there.
I bet that there are not enough libraries or the paths to them are set somehow wrong (they are indicated explicitly or they now lie in a different path relative to the exe)
