Anyhow, I don't expect you to be familiar with bat2exe converters.
I hate these bat2exe thingies since you always run from one problem to the next. I stopped using such tools a long time ago. Batch is a scripting language and if you need an executable then you should learn a programming language that can be compiled.
You should compress your files into a zip archive or create a self extracting archive.
As to your problem:
I don't find too long lines in my code and I cant see 1629 lines. Open your temporary cmd file to see why you get a peck of trouble. No idea what the bat2exe has done to the code
