Python Installer: “Error writing to file C:\Python27\pythonw.exe”

Question

I am trying to install Python 2.7 (64 bit) on Windows 10. In the middle of the installation, a window pops up saying:

Error writing to file C:\\Python

Answer 1

Your Windows 10 version may not be activated. So many administrator features are locked in inactivated Windows10 version.

So try to open CMD in administrator mode and run following command to ignore the activation message.

slmgr -rearm

Now you can install fresh version of python with pythonw.exe features.
