By the way, Dr. Troyer, when I go through the setup file for alps 2.2, alps cannot add its directory to the system path by default. I did it manually, maybe I messed up with the environment variables. Do you have any idea what the correct system path should look like ?

Dr. Troyer, I will uninstall alps-vistrails extension and also Vistrails and then do a clean installation of Vistrails and let you know. I am using Windows 7 Home Premium. Thank you.

You should not need to install alps-vistrails-2.2.b1-win32.exe then. Can you try just with a clean installation of VisTrails and tell me which version of Windows you use?

Yes Dr. Troyer, I also installed Vistrails 2.1.1.

Still when I try to run any ALPS project, I keep getting the error message "No module named pyalps." I don't understand why python is not able to import this module at all, and I also don't have any idea where this module is located.
