Hi,

We're planning to use setupbuilder to create an installer with autoupdates. When a customer's support contract runs out, we should be able to remove them from the autoupdates list, so they will no longer receive new software upgrades.

We're making the assumption that some of our customers may not be particularly tech savvy, so everything should be manageable on our end. Ideally, the system will be installed initially by a support engineer on site, and from then on any software upgrades should be done without the user really having to do anything.

Creating the autoupdate script is no problem. What I need help with is an approach to uniquely identifying a user and configuring the autoupdate script to only download the latest update if the user has a current support contract.
