In Windows, it is better to install development environments outside of the Programs Files folder because Windows has protections on that folder plus some other folders.
I suppose another alternative is to use the Wubi installer for Ubuntu or is there a better Linux one should be using. :)
Oooops!
The Wubi installer is not recommended for a computer sporting the Windows 8 logo or using UEFI firmware.
