hmm, have you put the `nimrtl.dll` next to lib.dll and main.exe? have you made sure that all binaries are compiled in 32 xor 64 bit?
I am using MinGW-w64 and have now added a little nim.cfg to the repo that makes sure that the compiler spits out 64 bit binaries. The Nim version I am using is 0.17.0.
