A quick search of the Internet as a whole revealed this:
http://www.pcmag.com/article2/0,4149,88432,00.asp
Which states:
COA2 runs under Windows 95, Windows 98, Windows Me, Windows NT 4.0, and
Windows 2000.
(Notice - No Windows XP.)
Also it leads you to:
http://www.pcmag.com/article2/0,1759,7822,00.asp
Which shows "Platforms: Windows 9x, NT, 2000, or ME"
But again - no XP.
None of which surprises me, as the applications is at Version 1.0 - Dated:
05-08-2001
So then I modified my search and looked for COA2 and XP. There were reports
of people having no issues using it with XP, but there were no details
either. There were some that even suggested other applications like:

Considering that COA2 would require someone to search the web and find it
for download for free or pay PC Magazine $6 to $20 for it.. I'd go with the
above.
