Missing Apple Mail Plugin after installation

I’m missing the Apple mail plugin after installation of Devonthink 2.0 pb7.
Using the help menu for re-installation did not fit the problem.

This is a Snow Leopard 10.6.1 problem that has been fixed for the next release. You can work around it by doing the following:

  1. Using the Finder, create the folder in your home > Library > Mail > Bundles
  2. Quit Mail. In the Terminal (found in Applications > Utilities), type the following:
    defaults write com.apple.mail EnableBundles -bool YES

Now go to Help > Install Add-ons and install the Mail plugin, it will work this time.

Also make sure to run Mail as a 64 bit application (until public beta 8 ships).
