Utility for viewing which files/dlls are loaded by an executable image

Visual Studio does it well. Use Tools > Attach to Process, Debug > Break All. Then Debug > Windows > Modules. For VS2015+ start that with Debug > Attach to Process.

use Process Monitor or Process Explorer.

The command line route is ListDLLs from Sysinternals.

It can list DLLs loaded by a process, or list processes that loaded a given DLL.
