Can you try the following?
- Do sum.py and product.py work?
- Are there any error messages with the --deferred-debug option? Maybe
you have to kill Python to see the messages if the program hangs.
- Does it work if you remove the following lines:
==
import viff.reactor
viff.reactor.install()
==

I have installed the program as detailed in the instructions, however
the test with millionaires.py appears not to be working. After
initiating the script millionaires.py on three different command
prompts all that I get is the sentence "I am millionaire X and I am
worth Y millions", but no result. I put some print-statements at
various positions in the code and the program does not appear to reach
line 80, where the comparisons have been done. What can I do?

I'm working on a WinXP SP3 Machine.
