Hi almanzo,
I seen that you are getting an error while trying to convert Iron Front. I had that same error but realized I missed a step entirely. While installing the converter allow it to make an icon for the desktop. Double click that icon and it will open another window, above the huge Start button there is another button that reads "create IF Arma". Click that and it will start the conversion, I actually thought installing the converter was all I needed and didn't realize I missed it completely. You're getting the exact same issue I was having. Once you start the conversion it will pop up another window and show the process. I hope this helps you oh and make sure the paths are correct, you'll see what I mean.
