When you install an OEM version of Nero it puts the OEM's serial # in these two registry keys:
[HKEY_LOCAL_MACHINE\Software\ahead\Nero - Burning Rom\Info]
"Serial5"="xxxx-xxxx-xxxx-xxxx-xxxx-xxxx"
[HKEY_CURRENT_USER\Software\ahead\Nero - Burning Rom\Info]
"Serial5"="xxxx-xxxx-xxxx-xxxx-xxxx-xxxx"
If you have proof of purchase, you can buy a registration # for a full version for $19.
With some cdr's going for as little as $40 after rebates, you really can't expect to get a full $50 (download price) version of Nero included.
$19 seems pretty reasonable to me, and you get to support a small company with a great product that many are pirating.
There is a place to enter the new serial # under help.
From Nero's FAQ:
"Q.: Nero came with my recorder. I bought another recorder, but Nero doesn?t work with it. Why not?
You have an OEM version that works only with the brand of recorder you bought. To use Nero with another recorder, you may purchase the full version for a small additional cost. Click here for details.
Note: When you order the update, you will need to have the serial number of your current version. If you don?t know your serial number, this is how you can find it:
Click the Windows Start button, then click Run.
Type the word ?regedit? (without the quotes), then click OK.
The Registry Editor window appears. In the data ?tree? on the left, double-click the corresponding keys until you have opened the following full key:
HKEY _CURRENT_USER\Software\ahead\Nero ? Burning ROM\info
In the box at right, double-click the name serial and write down your serial number"
