Issues in reading a SQL Server Alias registry key of 64 bit machine

Question

Hi All,
I am trying to read  values present in this Registry key Software\Microsoft\MSSQLServer\Client\ConnectTo.The Target system here is 64 bit machine.
All the Sql Server alias which has been set through the configuration manager has its information stored in the above key.

And when the Target system is 32 bit I am able to read the values which are present in the key.

Please help me in this Regards with your valueable inputs.
