Situation: installing Spybot-S&D on Vista.

Experienced: if the user does not elevate the installer (see FAQ), he might receive the following error message:Setup

Unable to execute file:
C:\Program Files\Spybot - Search & Destroy\SDWinSec.exe

CreateProcess failed; code 740.
The requested operation requires elevation.
Expected: use the runas verb when starting the service installation to enforce elevation. This is documented e.g. here (http://weblogs.asp.net/kennykerr/archive/2006/09/29/Windows-Vista-for-Developers-_1320_-Part-4-_1320_-User-Account-Control.aspx).
(SDWinSec.exe does already have the required execution level set, which seems not to be sufficient)
