Your procedure is what the developers are actually doing.
Here in the forums however, we suggest a more aggressive approach, one that doesn't simply launch the "installer.exe" as a simple/restricted user which is prompted by UAC later on, but with the right-click » "Run As Administrator"
(even if you are the Administrator) which prompts you for an Admin password from the get-go. That ensures that all the processes launched belong in the topmost access privilege group. That would be similar to some installers that have a shield in front of their icon, which is becoming more common these days...
I've been personally trying for quite some time to get the developers to implement this, but alas they don't want to unnecessarily increase the privileges without any fundamental reason. Security and all... The difference between the two approaches is that the forum recipe works even with the most stubborn of antivirus/protectors.

Nothing close like that in Greek, we should definitely adopt it, that's a really nice expression...
