Flash Builder 4.6 and Windows 8

When installing Flash Builder 4.6 on Windows 8, you'll find it behaves oddly when trying to import and debug an existing project. Bizarrely the debug button doesn't appear to run the app, and the window doesn't appear with your compiled Air app. The trace window oddly enough shows the app is running - but no visuals!

I suspected this was due to misconfiguration somewhere, but having recently done two Windows 7 installs and setups of Flash Builder I remembered not having to do this, so guessed it was a Windows 8 issue.

The solution to this (after looking through a lot of web forum postings - most of which didn't apply in my case as usual) was to make sure the application runs with administrator privileges. Presumably this was something to do with UAC, which of course I have switched off on my other machine.

To do this create a desktop shortcut to Flash Builder 4.6, and right click on it and set the options on its preferences.
