I too have purchased the CD from Costco, downloaded the Mac version and then went to download the Windows version. Even though the disk cover shows both Windows and Mac, the Intuit website will not give me the ability to download the Windows version. After 75 minutes on hold, Yolonda, the customer service rep, told me that this is a Costco issue! I questioned her as to how it can be a Costco issue, when Intuit produced the disk, packaged it and sold it to Costco. Costco is simply a reseller. Her reply was, it's a Costco issue and you need to take the disk back, get a refund from Costco and buy the program directly through Intuit!!
What wonderful education from Yolonda and a really sick feeling about Intuit!!
