Installation issues have been bothering me for a long time, and I need to find out where the problem lies -
If you try to run
C:\Qt\Tools\mingw1120_64\bin\g++.exe --versionfrom a Terminal do you get the following text:C:\Qt\Tools\mingw1120_64\bin $ g++ --version g++ (x86_64-posix-seh-rev3, Built by MinGW-W64 project) 11.2.0 Copyright (C) 2021 Free Software Foundation, Inc.
