I did not fully comprehend your issue.
But, do you not have a source control mechanism or a configuration management tool at your disposal?
It is terribly wrong to work without source control. An year without it is not forgivable at all.
The final installation will not have
setup.rul. You will have a compiled setup.inx sitting there. I have never seen any way to decompile it.
