Hi anonymous userBabuSubnivis-7461 ,
Please check if the normal user has full permissions to access to the dtexec.exe.
Please refer to dtexec Utility and An overview of the DTExec utility in SSIS.
The dtexec utility lets you load packages from these sources: the Integration Services server, an .ispac project file, a Microsoft SQL Server database, the SSIS Package Store, and the file system.
When you use the current version of the dtexec utility to run a package created by an earlier version of Integration Services, the utility temporarily upgrades the package to the current package format. However, you cannot use the dtexec utility to save the upgraded package.
