My favorite Twitter app, Twhirl died on me two days ago.  Actually, it’ snot Twhirl itself, the error message clearly identifies Adobe Air, stating the installation is damaged.

Fixing it should be easy: just reinstall Air.  Except… I can’t.  Adobe installer says: This version of Adobe Air is already installed on your system.   Yeah, thank you, I know, but it’s corrupted.

Oh, well, next step is uninstalling Air, then installing it again.  Except… I can’t do that, either.  A quick Google search shows I am not alone:  several users report that in Vista Adobe Air does not show as an installed application, hence you can’t uninstall it, either.

Catch-22.   I hope Adobe proves otherwise.
