--- Comment #7 from Anastasius Focht focht@gmx.net --- Hello JJ,
--- quote --- This got past the "Dao libraries" error. Now, after the splash screen and the program window opens, the error "CES has generated a .Net error. Value cannot be null. Parameter name: encoder" is displayed. --- quote ---
Nothing in terminal? There should be some (managed code) backtrace.
You could try 'winetricks -q gdiplus'. If that doesn't help then try 'winetricks -q windowscodecs'
Anyway, this kind of walk-though is now really going into end-user support area which Bugzilla was not really made for (-> winehq forums).
Regards
