Started Titanium 1.0 (Win XP) today. First it offered me to update Mobile SDK to 1.2.0; afterwards it offered me to update the application itself to 1.2.0. Immediately after clicking on the update link within the application, I got a modal window stating "Error: Missing installer and application has additional modules that are needed". This message reappears when I try to launch the application. I guess it's the same old song and dance: uninstall Titanium according to http://www.codestrong.com/timobile/howto/remove/, and reinstall it again. sigh
we're looking into this. it should pull down the latest SDK as needed.
Hey Christian, please try following the instructions here. You're on Windows XP, so your paths will be a little different. ProgramData is usually "C:\Documents and Settings\All Users\Application Data"
I did a complete reinstall already. FWIW, upgrade from 1.1 to 1.2 worked on OS X.
