So please mark this topic as SOLVED (button Topic Tools below your first post).

Thanks

Paths can be tricky on Windows

You're welcome !

Since you have it working now, please mark the thread as solved using the "Topic Tool" button so that other forum users may know a solution has been found :)

Just thought of something… Why not open the qtftp.pro file in Qt Creator and built if from there with the Qt version you are using for your application ?

@kuzulis Thanks a lot for the screenshot. very useful.
pardon me because of lots of my questions.
I got new error:

Could not start process "mingw32-make" INSTALL_ROOT="C:\Users\---\Documents\build-alaki1-Android_for_armeabi_v7a_GCC_4_8_Qt_5_5_0-Release\android-build" install Error while building/deploying project alaki1 (kit: Android for armeabi-v7a (GCC 4.8, Qt 5.5.0)) When executing step "Copy application data"

I searched and somebodies says you must set INSTALL_ROOT variable.
I dont know it is correct or not? if so how?
