Thank you for your question.
Let me start by point you to a useful page in our online documentation regarding the ArtOfTest Runner
. Specifically the section to note would be how to bring up the options menu using the following command 'ArtOfTest.Runner.exe /?'. The only relevant property you could change from here would be the path to the project root folder directory, however the correct folder structure within this path for Tests and TestLists would still need to be intact as you described. The .dll files along with the Bin folder are necessary because the .tstest file specifically relies on this structure. Buried within the .tstest file is a pointer to this bin folder and the name of the dll to load at run time. If the folder is not there, or the name of the dll does not match what the .tstest is expecting then you will get the error you are seeing.
I find when transferring a Project, simply creating a copy of the entire project folder (normally or through a zip file) and moving it to the Run-Time machine is the easiest way to escape all of these issues.
Let me know whether you have any further questions.
