Ran into an issue ,while adding a node to existing SQL Server Cluster .
Got the following error during install .
The current SKU is invalid.
After few google searches , found the workaround.
The workaround is simple. Clear the entry for PID in ....\x64\Defaultsetup.ini ( make sure that you copy this file to different directory) and manually type in the product key during setup. By following this workaround , the setup finished sucessfully.
You can see http://support.microsoft.com/kb/957459 for additional information . Per MS , this is fixed in the cumulative update.
