The current SKU is invalid - SQL Server 2008

This is an error you might get when when you try to install SQL Server 2008 or 2008 R2 to add a node to a failover cluster. As mentioned in the Microsoft KB Article:

FIX: Error message when you try to add a second node to a SQL Server 2008 failover cluster: "The current SKU is invalid"

http://support.microsoft.com/kb/957459

This problem occurs when you install SQL Server 2008 from a deployment share that uses a custom Defaultsetup.ini file, and this custom file includes the product key for SQL Server 2008. Additionally, this problem may occur when you install a second node for SQL Server 2008 from installation media that has a custom Defaultsetup.ini file that includes the product key.

While the resolution provided in the KB article to install CU1 for SQL Server 2008 might be the best step forward, unfortunately it did not seem to work for us. So we planned a work-around and it did work for us.

Even i have another solution. I had applied Service pack 3 (SP3) prior to add node and it worked perfectly fine.
