I've downloaded SQL Server 2008 R2 Developer (license key states
pre-pidded). Then I install the product with no problem. The license key is
defaulted in the setup. But after the install I wanted to add som features to
the install (wanted to add BIDS afterwards). Then I get this error and the
setup closes...
The SQL Server product key is not valid. To proceed, re-enter the product
key values from the Certificate of Authenticity (COA) or SQL Server Packaging.
Error code 0x84B40000
