re: "I...downloaded Regcure to scan my registary"
If I had just bought a new laptop and was having problems installing a legal copy of an application, I start with the either the manufacturer of the laptop or the application.
The last thing I would do is download and run a registry scanner/cleaner on a brand new machine, unless instructed to do so by the manufacturer's support staff.
But that's just me.
