VBA cannot find my DLL, despite hardcoding location.

It sounds like your DLL has dependancies on other DLLs that exist on your development machine but not on the target machine. When the OS loads your DLL but then can't find the dependent DLLs, it reports the same "cannot find file" error, making you think it cannot find your DLL when it really did. If that is the case, then you need to either distribute those extra DLLs or remove the dependencies on them.
