Package executing error

I wrote package using Integration Services and tried execute it on Visual Studio 2003 (Visual Basic). Package was loaded, but execute method has failed without any error messages. When I tried to run it on Visual Studio 2005, execution was successful.

Codes:

Dim App As DTSLib.IDTSApplication90 = New DTSLib.Application

Dim p As DTSLib.IDTSPackage90 = App.LoadPackage("d:\temp\Package.dtsx", True, Nothing)

p.Execute()

What can be the reason of the trouble?

Thanks,

Alexander

Only one .NET runtime can live in one process. Visual Studio 2003 uses .NET 1.1, and SSIS requires .NET 2.0 - so SSIS fails if the process has already loaded .NET 1.1.

You can use config file to change the .NET version used by applications developed with .NET 1.1 and force them to use .NET 2.0, but it will break Visual Studio debugging.

So it is highly recommended to use Visual Studio 2005. In Visual Studio 2005 you can also use managed API for SSIS - in Microsoft.SqlServer.ManagedDTS assembly, which is more convinient than using interop from DTSLib.
