I received the error in the attached screen capture. Turned out it was my fault since I'd missed the fact that I had a script included in project A (from which I was generating an exe), but it also turned out that one of the scripts in project A was in project B (which was used to generate a DLL and was "libraried" in the first script in A)
I kept generating the exe but not the DLL and kept getting the error shown.
My question. How do I debug a project that runs fine in RPC or as by double-clicking on the main .REX script in the "source" folder, but as soon as I move it to a folder where I have all the reginald dll's etc it bombs as shown.
I'd made some changes to the common script so it could handle generic files, so I kept on thinking there was a bug in MATCHNAME (since that was my "only" change I thought).
