Unable to load DLL 'hackrf.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E) about nethackrf

Hi. I checked x64 version of hackrf.dll with the dependency walker. I think that the only thing your computer can miss is vcruntime140.dll. Try to install Microsoft visual c++ redistributable 2015 or later version

P.S.: also make sure that all DLLs and your application are the same bitness.

Completely forgot about one more thing: before all of that above open properties of hackrf.dll and check that it's not blocked by windows. If so, click "unblock" button.

I installed the latest C++ redist package earlier today but no luck. I also checked with Dependency Walker earlier but must have missed some details. The MSVCR100.dll under PTHREADVC2.DLL is actually missing on the target. It's part of the VC++ redist 2012 version according to this:

I will get back with the results.

Had to go back one version, VS C++ Redist 2010 is required:

Now the problem is solved.

Interesting, I always thought that more recent versions of vc++ include older ones.

Could be an issue on Windows 11?

I've never tested it on windows 11.
After googling vc++ I discovered that all-in-one package from microsoft includes only 2015-2022 versions. So 2005 - 2013 can only be installed separately. I should mention that in readme file.
