Your first purchase will be of the Initial product, normally downloaded from the website, which will normally come with 12 months of free updates. On expiry of the free updates you may purchase an update subscription key to receive further free updates online yearly. Updates are normally produced every 4-6 weeks and your program will automatically detect new updates and offer to download them if you have unrestricted access to the web. You will also be advised by email each time a new update becomes available. Updates can also be downloaded and installed manually in the case of restricted servers. Each update is a complete product; after installation no further updating is necessary and details of all changes made compared to your previous versions are made available.
