Python 3.0b1, official MSI installer.

Checkout source code of this project:
http://code.google.com/p/anntools/

Enter into the root of your working copy and try to build a Win32 installer:

C:\Python30\python.exe setup.py bdist_wininst

NOTE: You might want to replace the path above with you Python
installation path. Please ensure, that Python 3.0 is used, since all
other versions from 2.4 to 2.6b1 works well.

You will get the following traceback during the build process:
