        Hi and welcome to devnet,

        Qt does not use Python, especially 2.7.
        What exactly did you install ?
        On which version of Windows ?

        On a side note, never install things like that in SysWOW64, you might compromise your system. Qt does not need that at all.

            Then I would recommend clean all the dependencies that were downloaded and rebuild an environment from scratch.

            I would also compare the environment variables between the computer where it works and yours.

              I found the problem. arm-none-gdb-py.exe was run during QT startup and an error was reported, but I don't understand why arm-none-gdb-py.exe was started when QT was run. I installed QT6.7 with the default configuration selected without adding other configurations。

                I don't either. It would be nice if you could translate the error messages to English.

                  This has nothing to do with Qt 6.7.2.

                  You have a gcc toolchain from https://developer.arm.com/-/media/Files/downloads/gnu-rm/10.3-2021.10/gcc-arm-none-eabi-10.3-2021.10-win32.zip

                  This toolchain ha compiled GDB arm-none-eabi-gdb-py.exe with Python support, but they have forgotten to include python27.dll in the package.

                  Unfortunately the newer versions of the toolchain at https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads do not include Python scripting for GDB.

                  Please file a ticket at https://developer.arm.com/

                    But, if you install https://www.python.org/ftp/python/2.7.18/python-2.7.18.msi then you will get arm-none-eabi-gdb-py.exe starting!
