When I start Pycharm, this python setup menu pops up.

Python 3.7.4 is not even the version I'm using. Everything else works fine and I can just close it, but it is annoying.
There was a [same question](https://stackoverflow.com/questions/35699169/why-does-the-python-installer-keep-popping-up), and the answer was

> 
> You appear to be using the installer .exe as if it were the Python interpreter. Install Python to somewhere first, then use the python.exe in the bin directory inside that.

But I can't find where my bin directory is. My Python37-32 folder looks this.

How do I find my python interpreter?
