PyCharm asks for python interpreter every time project is loaded

Question

Rather frustratingly, every time I load up an existing project or create a new one - it complains there is no interpreter selected and I have to provide the path to it.

There is nothing unusual about my python installation, it's sat in C:/Python27/ as you would expect. It always used to work, but the last few weeks something has changed.

I'm running Win7. PATH system variable points to C:/Python27/ as it ought to.

If I crack open commandline, the python command opens as it ought to.

Any ideas?

There is no Default Settings any more, It's called Preferences for New Projects in the newer versions of PyCharm (my version is 2018.3.3).

For that, go to :

File > Preferences for New Projects > Project Interpreter
