I use Construct2 on my surface pro / laptop and desktop depending on where I am working. To make things easier I installed my C2 on a USB 128gb pen along with my projects. It works great and makes things easy in terms of updating apps from my various devices.
What I am having trouble with is trying to setup the NW.js exporter in the same way. I tried to install directly to the pen drive but C2 still tells me that I do not have NW.js installed when I try and export. Is this due to C2 always looking for NW.js int he C:\ drive? Is there a way to set this up?
