Create a Windows process to check silently for missing DLLs

I want to check if all the required DLLs are installed for an executable, so I run it with CreateProcess, and I check the exit code.

Problem: Windows displays a popup saying the DLL was not found, then displays a popup saying that the program has stopped working.

How can I avoid all these error popups?

Anyway this won't cover all the problematic cases. Your process may be dependent on delay-load DLLs. You may check your executable by the dependency walker tool (or similar).

However your process may try to load more DLLs at runtime (via LoadLibrary or similar).

You need to call SetErrorMode passing SEM_FAILCRITICALERRORS.

The SetErrorMode is a slightly tricky API to use since you need to merge the new mode with the existing modes. Raymond Chen explains how to do it correctly.
