Pycharms and GAMS

Hello,

I am using the modeling software gams and I am trying to connect to their python api. To do that I need to run a file which is called setup.py. I tried this in cmd and it worked perfectly. Now I tried to do the same with Pycharm and I noticed that my interpreter is the 32 bit version of python and then it gives an error. So I added the 64 bit python 3.6 interpreter in Pycharm, but I can't seem to install the module for it. I tried :

py -3.6 setup.py install

And I noticed that the module is installed in the 32 bit interpreter in Pycharm but not the 64 bit interpreter.

Can anybody help me solve this problem? 

Thanks!
