On Windows 7 SP1, I'm experiencing intermittent exception(s) launching ReactGrid, ReactReduxSpa. Exception details can be found below. I have not been able to repro on my Win10 machine using Chrome, IE, or Edge.

First, I suspected it was a MAXPATH issue because my content dir was several levels deep, but I cloned the repo into a short path C:\Git\JavaScriptServices\ and am still experiencing this behavior. I've also noticed that ReactGrid and ReactReduxSpa (AFAIK) are the 2 React projects that employ SSR. I haven't been able to repro this on Windows 7 SP1 with the simple (CSR-only) ReactSpa using Chrome 50 or IE 11.
