The Installation screen is non-standard and contains big red-colored buttons and graphics. But since you only have to go through this step once on each computer, it's easy to let it slide for the functionality it offers. The interface is in the form of a browser plugin which is available for Mozilla Firefox and Internet Explorer, and a web-based management interface if you're on an untrusted system or cannot install plugins/extensions on that computer.
The interface offers a lot of choices for seemingly minor things. For people who want to just setup-and-go, this can get a bit frustrating. For people who love to configure each option according to their needs, this is heaven. For example, you have an option to set the timeout after which the clipboard will be cleared. It's one of those things which can go either way, and your mileage will definitely vary.
