Failure When Executing SSIS Package From C# On Machine Different Then SQL Server

Hi everybody,
I'm newby in SSIS. I have been using DTS in SQL 2000.
Trying to learn how to execute SSIS package from C# code of ASP.NET web server.
Here's my case:
1. SSIS package with simple data transformation from one table to CSV is stored in SQL Server 2005 storage
2. CSV is for simplicity placed in C: .txt
3. I haven't used SSIS configuration files
4. Protection level of package = EncryptSensitiveWithUserKey
5. Executes OK from Bussiness inteligence studio
6. I've created console application with this code:

...
sqlServeruser = "sa"
...

Package package = app.LoadFromSqlServer("Export_vw_TestConsumerPerson", sqlServer, sqlServerUser, sqlServerPassword, null);
DTSExecResult result = package.Execute();
Console.WriteLine("Package Execution results: {0}",result.ToString());
...

7. When I connect through Remote Desktop Connection I successfully execute this console application on SQL server host machine.
8. When I try execution from computer where I develop package and where I successfully executed it from Bussiness inteligence studio I'm geting FAILURE was a result

Connection params for SQL are same in console application and in SSIS project of Bussiness inteligence studio.

Thanks for any hints
