It went pretty smoothly, but there's at least one gotcha so wanted to share the steps in case anyone else wanted to do it:</div><div class=""><br class=""></div><div class="">1) Download the the Win10 ISO from this page: <a href="http://windows.microsoft.com/en-us/windows/preview-iso" class="">http://windows.microsoft.com/en-us/windows/preview-iso</a> - there's also a product key there</div><div class="">2) Install the Win10 guest OS as a VM</div><div class="">3) Mount a shared folder inside the guest OS pointing to the firefox source checkout in the host OS</div><div class="">4) From the guest, navigate in the shared folder to the objdir/dist/bin/ and open firefox.exe</div><div class="">4a) The part that tripped me up was that opening firefox.exe from the guest caused a silent failure. I needed to install "Visual C++ Redistributable Packages for Visual Studio 2013" in the guest OS: <a href="http://www.microsoft.com/en-us/download/details.aspx?id=40784" class="">http://www.microsoft.com/en-us/download/details.aspx?id=40784</a>.</div><div class=""><br class=""></div><div class="">Brian</div></body></html>
