Attempting to run SSIS packages using dtexec.exe, I got this error message:
Could not load package "D:\Filename.dtsx" because of error 0xC00160AE. Description: Connecting to the Integration Services service on the computer "" failed with the following error: "Access is denied." By default, only administrators have access to the Integration Services service. On Windows Vista and later, the process must be running with administrative privileges in order to connect to the Integration Services service. See the help topic for information on how to configure access to the service.
Typically for Microsoft, there's no clarification about which help topic has this information. Certainly the
dtexec /? help does not.
Running dtexec from a command prompt launched with admin privileges, or from an application with admin privileges, did not resolve the problem.
