Unreal.js

So this is the error I run into,

Anyone else try this on Win10, VS2015?

$ cd Unreal.js/Examples/Content/Scripts && npm i
Error: EPERM: operation not permitted, mkdir ‘C:\Program Files (x86)\Git\Unreal.js’
at Error (native)

Error: ENOENT: no such file or directory, open ‘C:\Program Files (x86)\Git\Unreal.js\Examples\Content\Scripts
pm-debug.log.36f31f097e76036e95a7573b8d6cb22c’
at Error (native)

Has anyone come across this - and if so can you plz tell me how you fixed it^?
