Rebuilder (Music replacement version) errors when clicking "Run"

[DiskyNorsk]

i don't know if it has anything with the app version to do, but whenever i click Run, this error pops up

The error says it couldn't find ISLE.EXE at %Temp%\LEGOIslandRebuilder, and if i put ISLE.EXE into the folder, for some reason it deletes ISLE.EXE and throws the exact same error.

if it helps, here's the error log it spat out (translated to english from norwegian by me by me):

See the end of this message for detailed info on activating
JIT-debugging (Just In Time) instead of this dialog.

************** JIT-debugging **************
Når du skal aktivere JIT-debugging (Just In Time), må .config-filen for dette
programmet eller datamaskinen (machine.config) ha
jitDebugging-verdien angitt i delen system.windows.forms.
Programmet må også kompileres med debugging
aktivert.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

Når JIT-debugging er aktivert, blir alle ubehandlede unntak
sendt til the JIT-debugging som er registrert på datamaskinen,
i stedet for å bli behandlet av denne dialogboksen.

I know this doesn't solve the issue, but maybe consider looking into SIEdit? It's more capable and better updated, and it does allow the substitution of audio files within the game. It would allow you to use the more modern Rebuilder version while also updating the music if you wish.
