It is supposed to prompt you for a location to install the wxPython files.  The default location is wherever your $ProgramFiles/E-ons Software folder is.  Perhaps it's not picking this up on Vista.

The WXPython installer did not get the right folder. It proposed *C:Program Files/*e-on Software/Vue 7 Infinite. And when I changed this manually, I was not sure it installed it in the right place.

But is works OK now, including on Michael 4. I took advantage of the update to make a test and a post on my website. 

One question: when importing a character with hair as a separate object, I assume I have to choose only the character body, not the group, before swapping materials?
Also, I get a small error message when I choose a character on which materials have already been swapped, but it is not really a problem.
