+  - You cannot use the stock gcc/g++ because it is too new and not compatible with Qt 5.9. So you will have to fetch the 5.3.0 version from the archives:

+  - Open the command console with the shortcut you created

 The final packaging is done with the `windows64.install.bat` utility. Assuming `D:\development\sdrangel` is the root directory of your cloned source repository, `D:\msys64` is the installation directory of MSys2, `D:\softs\libusb-1.0.20\MinGW64` is your libusb installation directory and `D:\Programs\sdrangel64` is your target installation directory do: `D:\development\sdrangel\windows64.install.bat release D:\Programs\sdrangel`. Modify the script if your MSys2 and libusb locations are different.
