Hi @aoleynikov. I prefer the technique mentioned in Rick's next article where you don't select the addon in the projectGenerator, and instead add it later by hand along with the property. I think it should work either way though.
If you're using OF 0.8.4, make sure you're on the 0.8.4 branch of the addon.
If you're using OF 0.9 from GitHub, then the master branch of the addon should work (hopefully example & exampleBodyIndexColor work too 
) though you will have to use a newer version of VS (2015 definitely works, 2013 might).
Let me know if that works!
