:-D Don't know - You are the AIR programmer here!... :-D

Anyway, I found what the problem was.
Not only AIR wants an installation, but it even requires an administrator account to be installed, like it would register libraries or install services... Thank god they don't require the pope to install it, so I managed to install it all right. Everything runs fine.

Since I'm sure I'm not the only person working in a non-privileged account, and you can't sudo AIR stuff (it's not recognized as executable by Windows, so no "run as" option), I'd suggest adding to your installation instructions that people need to be logged as administrators.

No, it's a local hard disk.

Another question, once it's installed and has found its uiCommand.bbml, can one delete the initial installation folder ("LuxPoseUI_0.1.2"), or does it still requires the stuff in there?
