OK, I think this should be fixed now. Can you grab the latest version of the compile engine and let me know how you get on? If you’re on mac, you need to remove JUCECompileEngine.dylib from Projucer/Contents and also user/Library/Application Support/Projucer and if you’re on Windows you need to remove the .dll from next to the Projucer.exe file (if it’s there) and \Users\username\AppData\Roaming\Projucer-version number. Then when you re-open the Projucer it should prompt you to download the newest compile engine.
