It related to a function I run at the very start of the program launch to verify another instance of the application was not already running. That code had the Operator/operand error, but would only happen under certain conditions. Easy fix once I knew where the line of code for the error was.

BTW, I also saw it right away that it was code related :) The error message itself was very informative. You would have gotten a different error in case of not finding run-time libraries.
