I'm told the key code is incorrect.
Who told you?
Where are you getting the Product Key?
What program are you trying to enter the Product Key into?
Why are you entering the Product Key? (did the software ask for a new product key, are you reinstalling...so on)
What is the error message you receive? (full message, don't paraphrase)
At what point do you receive this error message (if any)?
Lastly, download and run the Genuine Diagnostics tool (MGADiag.exe) at this link http://go.microsoft.com/fwlink/?linkid=52012. Click "Continue", click the "Copy" button then “Paste” the report into a reply message in this thread.
If you do not have access to the Start Button:
1) Login to Vista and click the option that brings up Internet Explorer.
2) Type: http://go.microsoft.com/fwlink/?linkid=52012 into the browser address bar.
3) A window will come up asking if you want to “Run” or “Save”, Select “Run”
4) When the program runs, click the “Continue” button, then click the “Copy” button.
5) Return to this thread http://social.microsoft.com/Forums/en-US/genuinevista/thread/69a85ead-eb5f-49f1-b8f2-e047d2680f54.
6) In a reply post, paste the Diagnostic Report.
Thank you,
