I'm on Windows 8.1, using a brand new install on a new install of Windows, Appcelerator Studio build 4.0.0.201505202026 trying to get either even just an empty Alloy project to run. The following is the console output from the emulator failing to launch, but the results are about the same when trying to launch it on an actual device, or trying to build the project for Mobile Web. I've tried downloading all of the Android SDKs (twice), reinstalling Appcelerator Studio, and many random 'fixes' suggested to other who've run into similar error messages, all to no avail.
