I presume that this is supposed to be a Windows PE file (DLL or EXEcutable). You can use the depends utility for Windows to take a peek at the references that the module is trying to load. There will be a shitload of "API interfaces" that cannot be found that you can ignore such as anything that starts with "API-" or "EXT-" plus several other obviously Microsoft named "magic" (the files do actually exist it is just that depends does not know how to find them) You can find depends here (self-contained executable file): <https://www.dependencywalker.com/> See also another version that requires a "poo load of dependencies that are included" but can work from the command line: <https://github.com/lucasg/Dependencies> Both of them install in the "old fashioned manner" as in unzip and put in the path, none of this "run a silly installer that fills the computer with malicious crappola" that is so common in these days of Eternal September.
