Unable to load DLL: "aws-cpp-sdk-core.dll", Status: 0xc0000135

I generated the AWS SDK projects for 32-bit using this command:

cmake .. -D CMAKE_BUILD_TYPE=Release -A Win32

Then I built the AWS SDK using Visual Studio 2019, running on 64-bit Windows 10.

Ultimately, the goal is to use the AWS SDK from an ancient C++ compiler being used to build legacy software applications. On its own, it'd never be able to build the AWS SDK, so I was going to write a "bridge" DLL (using Visual Studio 2019) to work between the old compiler and the AWS SDK DLLs.

When I tried to load my bridge DLL using LoadLibrary(), the DLL couldn't be loaded, and GetLastError() returned 126.

That was from the old compiler, but I also received the same result from a test project in Visual Studio 2019. I enabled loader snaps with gflags.exe on the VS sample program, and then I saw this:

Next, I tried skipping my bridge DLL and loading aws-cpp-sdk-core.dll instead. That resulted in similar errors, except now it couldn't find aws-c-event-stream.dll.

When I tried loading aws-c-event-stream.dll, it gave the same errors again but complained about not finding aws-c-common.dll.

Finally, I tried loading aws-c-common.dll using LoadLibrary(), and that worked!

I found a question related to building AWS for 32-bit, which leads me to wonder if I'm not actually building it correctly for 32-bit Windows. is it possible to build aws-cpp-sdk in 32 bit?

Is the AWS SDK supported for 32-bit? If so, what step am I missing?

Thanks!
