Check the upgrade matrix

Check the upgrade matrix on Microsoft's site. You should have done this prior to purchasing. Would have saved you what's likely going to be a very expensive mistake, given you generally can't return opened software.

According to Microsoft's website

According to Microsoft's website, you have to do a clean install if you want to run Win7 Pro and you currently have Vista Home Premium.

http://www.microsoft.com/windows/windows-7/get/upgrade-considerations.aspx

You'll note that the Vista Home Premium and Win7 Pro intersection has the yellow star, which, according to the key, says that a clean install is required.

So, I don't know what you were looking at, but it's pretty clear cut as far as the official upgrade matrix is concerned.
