+<p><b>Note:</b> On Windows systems we suggest using a service to run Openfire (read the Windows Service section below). When using Openfire Launcher on Windows Vista or newer with UAC protection enabled, it has to be run with Run as administrator option, to be able to write changes to config and embedded database (if used) stored in <tt>C:\Program files\Openfire\</tt> folder. If Openfire is running via launcher without Run as administrator option from Program files it can't get proper permissions to write changes. It shows errors (in red) when running the launcher and during the setup will require the current password for the administrator account (although this is a new installation and normally it doesn't ask for it). This is an effect of missing permissions and Openfire not being able to initialize the database and other resources.</p>
