Base game incompatibility and launcher version glitch

The Base Game incompatibility and launcher version glitch could occur in The Sims 3 game Launcher after players updated The Sims 3 to the latest patch. Players may have experienced the Launcher reading their game versions as 0.0.0.0 or get a pop-up message saying: 'Base Game Incompatibility'. This was apparently a recurring problem when updating as it was posted on TheSims3.com whenever a new patch was released, although it no longer affects new users as The Sims 3 has stopped receiving updates.
It was first posted as a sticky on June 14, 2010 by SimGuruPopTart at the technical forum and was bumped up when EA released a new patch.
