Usually you just need to download the latest installer from our Downloads page. As new versions of Vegas Pro and Movie Studio are released, we do not need to update our plug-ins but we do need to update the installer to find the new version. What we do is update the installer but maintain the same version number of the plug-in since it hasn’t changed. It’s always good to re-download the latest installer from our Downloads page even if it has the same version number as the one you already have. While the plug-in will be identical, the installer will be updated to recognize new versions of Vegas Pro and Movie Studio.
