Comment 8 for bug 1207712

On the other hand, it looks like you migth need to do a new wineconfig with the "export WINEARCH=win32". My workaround was to move .wine to .wine-64 (just in case you have something there that you want to backup). Then, set the WINEARCH to win32 and run the winecfg to create the new .wine. Alternatively, you can use "export WINEPREFIX=$HOME/.wine-32", then create a new .wine-32 configuration when you run winecfg (to set your prefered version). Hope that this helps...
