No, it's not fixed yet...
I did some investigation and I think this problem may actually be an IE issue.
I found the index.htm file for the registration in:
<install_bottle_dir>/drive_c/Windows/profiles/All Users/Application Data/Intuit/Quicken/Inet/Common/Pnf/Reg
Opening this file in IE causes IE to crash, but opening it in a linux-based firefox window results in a error message generated from within the javascript of the page.
