Custom install and start windows service when using electron-builder

Question

I've figured out how to install a windows service that manages a server (server.exe) when the user install the app via the ElectronBuilder.exe created when I package the app.

However, the Windows Service does not start in the install. I had to manually go into services and then start it.

I can't seem to figure out whats wrong with my script and would appreciate someone taking a look! Thanks! (p.s. I assume this shoould be possible)

Here is installer.nsh found in ./build

!macro customInstall
  DetailPrint "Installing DialogixService..."

  ; 1 Install service with NSSM, pointing to your Node-based EXE
  ExecWait '"$INSTDIR\resources\assets\nssm.exe" install "DialogixService" "$INSTDIR\resources\assets\server.exe"'

  ; 2 Set the service to auto-start
  ExecWait '"$INSTDIR\resources\assets\nssm.exe" set "DialogixService" Start SERVICE_AUTO_START'

  ; 3 Start the service
  ExecWait '"$INSTDIR\resources\assets\nssm.exe" start "DialogixService"'
!macroend

!macro customUninstall
  DetailPrint "Uninstalling DialogixService..."

  ; 1 Stop the service
  ExecWait '"$INSTDIR\resources\assets\nssm.exe" stop "DialogixService"'

  ; 2 Remove the service
  ExecWait '"$INSTDIR\resources\assets\nssm.exe" remove "DialogixService"'
!macroend

Here is my Electron-Builder package.json
