Biztalk cofiguration error Nº 1

After tens of BizTalk installations I decided to post a collection of errors found.

The first one it's an easy one!

The error:

While you are in the BizTalk configuration wizard, with BAM configuration, you get this error:

ERROR: Failed to set up BAM database(s).
There was a failure while executing nscontrol.exe. Error:"Microsoft Notification Services Control Utility 9.0.242.0

The Solution:
You need to solve the problem in 2 steps:

1. Install SP2 of SQL 2005 Notification Services
2. Copy the DLL to the GAC
1. Open a CMD console with administrator privileges and run:

C:\Windows\assembly\GAC_MSIL>copy Microsoft.SqlServer.Instapi\9.0.242.0__89845dcd8080cc91 c:\Microsoft.SqlServer.Instapi\9.0.242.0__89845dcd8080cc91\Microsoft.SqlServer.InstApi.dll 

C:\gacutil.exe /i Microsoft.SqlServer.InstApi.dll
