Extract and run .exe during uninstall

Hi All

Task:
I need run special application during uninstall process.
It's .exe file, not .dll. And I cannot make .dll from .exe and use plugin NSIS mechanism 🙁

How i can include this .exe file in my setup and temporary extract it during UNNINSTALL process ONLY and run?
Any idea?

Section Uninstall



File "/oname=$TEMP\myapp.exe" "myapp.exe"

nsExec::Exec "$TEMP\myapp.exe -params"

Delete "$TEMP\myapp.exe"
