Base game incompatibility and launcher version glitch

The Base Game incompatibility and launcher version glitch can occur in The Sims 3 game Launcher after players update The Sims 3 to the latest patch. Players may experience the Launcher reading their game versions as 0.0.0.0 or get a pop-up message saying: 'Base Game Incompatibility'. This is apparently a recurring problem when updating as it is posted on TheSims3.com whenever a new patch is released.

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.
