You seem to be applying a reverse burden of proof there - software is guaranteed to work in all not-yet-released Operating Systems unless a specific disclaimer is issued? Sorry, things don't work that way in the USA or in Australia.
Have a look at the System Requirements for Creator 2009, they're printed on the box and the adverts.
Do you see Windows 7 mentioned there? No, the advertised platform for Creator 2009 is Windows XP and Vista.
As for the exchange rate for the $AU, blame your present Prime Minister or Treasurer not Roxio.

Seems you have difficulty understanding our obviously different use of english here in our quaint little part of the world so I will restate things.
The AU dollar is nearly 1 for 1 with the US dollar yet the upgrade price from Roxio Australia is over twice the US dollar price ( I would have to pay over 100 USD to purchase the upgrade). That is a Roxio Australia pricing issue not a political party financial policy issue.
I did not ask for a gaurantee that 2009 would work in any as yet unknown future released OS. What I am saying is that at the time I purchased , Roxio was obviously finishing testing or in the final stages of preparing 2010 for Windows 7 and that as a customer curtesy they could have mentioned 2009's incompatibility with a simple link to the compatibility pages.
Saying something like you should have read the fine print is arrogant behaviour which given your approach to me as a Roxio Guru is now completely understandable.
No matter I have the last say as Roxio has lost a long term and until now loyal customer as I have purchased and used every version since 1997 spending with my businesses and myself spending 10's of thousands of dollars. In your own arrogance you are saying like it or lump it, well I lump it as is my right I will now shop elsewhere
