A very common question is that :
what is minimal requirements for run a package?
Minimal Requirements to run SSIS package is :
DTEXEC which can be installed with Integration Service at the SQL Server setup media. Note that you should Install Integration Services, because if you install DTEXEC without Integration Service then you will got this message when you try to execute a package from DTEXEC command line:
The SQL Server Execute Package Utility requires Integration Services to be installed by one of these editions of SQL Server 2008: Standard, Enterprise, Developer, or Evaluation. To Install Integration Services, run SQL Server Setup and select Integration Services.
This is same operation on a machine who has Integration Service Installed:
Another option to execute SSIS package is with BIDS, you can select it during SQL Server setup steps.
So as a result you need to have one of these options to run a package on a machine: SSIS or BIDS.
