NIS2009 and Windows 7

I have read several threads about Windows 7 and this appears to be an issue that has not been adddressed.

 

I purchased NIS 2009 earlier this year (3 PC license).

I have only activated 1 license.

mynortonaccount verifies this.

 

I recently updated my 1 installation of 2009 to 2010.  Works fine.

 

I just purchased a new computer.

It came with Win 7 Home Premium preinstalled.

I inserted my NIS 2009 disk in the DVD drive and got the message that XP or Vista is required.

 

So i can't install NIS 2009 on my new Win 7 computer.

That means that I can't update it to NIS 2010, which _would_ work.

 

How do I make this work?
