For Windows users who may be unaware of how to start an administrator (elevated privileges) command prompt ... one of the easiest ways is from the Start menu. Go to Programs->Accessories; then right click on "Command Prompt" and select "Run as Administrator."

You'll have to cd to the directory where you saved "launcher_updater_20141204.zip", of course, before running the python command to launch the updater.

If you need to do this kind of thing a lot (like me), that whole "cd"-ing around can get to be a pain in the butt. I've found a fairly simple script that will add a context menu item to Windows Explorer. It allows you to right-click on any folder in Windows Explorer and select "CMD here as Admin." You get the UAC prompt and, BOOM ... an command prompt in the correct folder with elevated privileges.

It's a registry text file (*.inf) that you right click on and choose "Install". It also provides an uninstall option in the standard add/remove programs should you want to get rid of it.

It's only for Vista and Win7, since Win8 already has the feature and XP doesn't need it. I'll post it if there's an interest.
