To get Trac 0.11 working on top of the BitNami Trac Stack for Windows, you need to do the following:

• Launch the command line console (Start Menu -> Run -> type cmd)
• Change directory to your Trac installation.
• Load the environment variables by typing “scripts\setenv.bat”
• Change directory to python\Scripts
• You can install trac 0.11 by typing “easy_install http://svn.edgewall.org/repos/trac/branches/0.11-stable” from the console
• Stop the servers using the Start Menu shortcut
• Copy the folders DLLs and Lib from python\ to apache2\bin
• Restart the servers
• The last step is typing from python\Scripts ‘trac-admin “(PATH TO THE INSTALLATION)\projects\(NAME OF THE PROJECT)” upgrade’, substituting PATH TO THE INSTALLATION and NAME OF THE PROJECT accordingly.
  
  That’s all :)
  
  Cheers
  
  PS: We’re waiting for the final version of Trac 0.11 to make the new version of the stack
