I started getting the error message today that Node-Webkit was not available as a preview browser. I noticed that the nw.exe was missing from the win32 folder in exporters/html5/node-webkit.
I thought that I just needed to reinstall Construct 2 and that would solve the issue. No dice, I'm now getting this error message when I try to reinstall Construct 2:

Has anyone else come across this issue?
