I've googled for a solution, and based on that, let me report a few details:

I've tried 32-bit PyScripter-v2.6.0-Setup.exe with 32-bit python-3.6.1.exe; and 64-bit PyScripter-v2.6.0-x64-Setup.exe with 64-bit python-3.6.1-amd64-webinstall.exe.

I'm on a 64-bit Windows 10 machine.

I uninstalled other versions of Python on the machine.

Tried unzipping rpyc in the \Lib\ folder, as someone suggested that [here](https://github.com/pyscripter/pyscripter/issues/608).

What else should I be looking at?
