Debugging has failed

[OlegK]

Hi all,
I am trying to use QtCreator to debug my test application but unable to start it in debug mode:
This is debug log:

Note: This log contains possibly confidential information about your machine, environment variables, in-memory data of the processes you are debugging, and more. It is never transferred over the internet by Qt Creator, and only stored to disk if you manually use the respective option from the context menu, or through mechanisms that are not under the control of Qt Creator, for instance in swap files.
wYou may be asked to share the contents of this log when reporting bugs related to debugger operation. In this case, make sure your submission does not contain data you do not want to or you are not allowed to share.

My environment:

• Windows10 x64,

• Qt Creator 4.6.0

• Qt 5.10.1

• MinGW 5.3.0 32bit for C++

What am I doing wrong, where is my mistake and how to solve that issue.
Thanks a lot.

@OlegK Try to install Python 3

[OlegK]

Python 3.6.5 fixed my issue.
Thanks.

[xenovas]

hi ,

I have exactly the same issue and i don't want to install python 3... is there any other way around ?

[xenovas]

how about changing to MinGW 64 ?
