Can't Execute Community Version of PyCharm

I am trying to run community version of Python. I had previously installed the professional version which is no longer available.

It is giving me some setting problem. I can’t go beyond that. I want to store python files in D: because my C: derive has just 15 GB space. I am getting message:
Directory D:\ is not empty. Would you like to create project from existing resources?
I have tried pressing Yes /No/Create several times but I can’t go beyond that. I have attached the image:

Cant Execute Python using Community version2

Somebody please guide me.
