Oh, sorry - I was suggesting that you use the develop branch. All of our recent work goes onto the develop branch, which is then periodically merged into the master branch. The Code::Blocks fixes are new enough that they haven’t made it to the develop branch yet.
The Projucer executable is only distributed in direct downloads. When you clone from github you’ll need to compile the Projucer manually. On Windows the way to do this is to open extras/Projucer/Builds/VisualStudio2015/Projucer.sln in Visual Studio 2015 and build the solution. Visual Studio Community is free and the recommended way of creating JUCE apps on Windows. We rely on the forum to report Code::Blocks exporter errors but Visual Studio is internally tested.
