I’ll leave the first question for Chris. He’s a lot more familiar with trap-engine’s guts than I am, though it’s possible that resolving the second question will get it to do what you want.

Rebooting doesn’t do anything as far as GnuCash is concerned so you can save yourself the time required to do it.

Guile compiles its .scm sources into .go files. The ones that are built while packaging GnuCash are in c:\Program Files (x86)\gnucash\lib\guile\2.2\site-ccache\gnucash. If you edit share\guile\site\2.2\gnucash\report\trep-engine.scm directly guile will notice that the timestamp on the file is later than the compiled file and recompile it; the new compiled file will be written to a cache directory in your Home directory. trep-engine is imported with “(use-modules (gnucash report trep-engine))” so to substitute one in a different directory it has to be  “…\foo\gnucash\report\trep-engine.scm” and “…\foo\” has to appear before c:\Program Files (x86)\gnucash\share\guile\2.2\site\” in GUILE_MODULE_PATH.
