When debugging stored procedure, getting error: "Interface not registered on client. SQL Serve (4326559)

While performing remote debugging, I encountered the error message:

   "Interface not registered on client .  SQL Server 2005 client  may not be properly installed."

Remote Debug Components are not installed or registered on the workstation running Toad. From Toad for SQL Server Support Bundle (Help | Support Bundle), it shows that the SQL Server debug registry keys are not found.

1. If you don't have a SQL Server Client installed on your workstation, then the client you want to download is located in the following Microsoft Site:

    http://www.microsoft.com/downloads/en/details.aspx?FamilyID=536fd7d5-013f-49bc-9fc7-77dede4bb075&displaylang=en#QuickDetails

    If your OS is 32-bit grab sqlncli.msi.

    If your OS is 64-bit grab sqlncli_X64.msi.

2. Register your ssdebugps.dll

    a. By default, go to C:\Program Files\Common Files\Microsoft Shared\SQL Debugging\ssdebugps.dll or search for where it is on your drive
    b. Unregister it first.  Go to Start | Run and copy and paste the following:

              regsvr32 /u "C:\Program Files\ Common Files\Microsoft Shared\SQL Debugging\ssdebugps.dll"
