Make sure you have installed the VST Suite first.

To check for updates you need to run the VST Suite, you can run the VST Suite from your start menu (Start > All Programs > Sealey > VST Suite) or from the VST Notification Icon* found in the left hand tray at the bottom of the screen (Right Click and select VST Suite)

Next click Get VST Updates and follow the instructions.

*The notification icon is a tool we use for informing you of new application releases, if you click "Check for VST Notifications" this only checks if we have sent you a new notification, it does not check if your VST is up to date.
