I don't see how that's possible. The double dots in your original code seem to imply that you want to go up one level and then into the Detector folder. If the Detector folder was in the same folder as your EXE then the first code snippet from post #9 would work and the second wouldn't.

I'm guessing that you have manually gone into the 'bin' folder under your project and added a Detector folder there. Am I correct? That's no good because that's not where it will be once it's deployed.
