The V2 Expansion is the same as "WOFF 2", so if you bought the bundle, then you should have had two downloads from your purchase. The first for WOFF and the second for the V2 Expansion.
Download and install WOFF
Download and install the V2 Expansion
Now all you have to do is update to the most recent patch version.
Download and install the V2.16 patch update.
The latest patch contains all previous patch changes within it, so there is no need to download any previous patches for V1 or V2.
