problems running SSIS routine from command line

Can't run SSIS package from commend line

tried all the locations of DTExec.exe on machine

I have a basic SSIS package that reads files and loads into database. (runs fine from SSDT)

tried the following command lines :

"C:\Program Files (x86)\Microsoft SQL Server Management Studio 18\Common7\IDE\CommonExtensions\Microsoft\SSIS\150\Binn\DTExec.exe" /File "C:\test_ssis\importStuff.dtsx"

<i belive this is the installation for SSDT, but could be wrong!!>

"C:\Program Files (x86)\Microsoft Visual Studio\2017\SQL\Common7\IDE\CommonExtensions\Microsoft\SSIS\150\Binn\DTExec.exe" /File "C:\test_ssis\importStuff.dtsx"
"C:\Program Files (x86)\Microsoft SQL Server\110\DTS\Binn\DTExec.exe" /File "C:\test_ssis\importStuff.dtsx"                             
"C:\Program Files (x86)\Microsoft SQL Server\120\DTS\Binn\DTExec.exe" /File "C:\test_ssis\importStuff.dtsx"                             
"C:\Program Files (x86)\Microsoft SQL Server\130\DTS\Binn\DTExec.exe" /File "C:\test_ssis\importStuff.dtsx"

which correspond to all the locations i could find DTExec on the computer

running first commmand line gives:

all the others give somethign like :

I think some googling implied that both these seemed to be something to do with the version?

but I am confused as surely ONE of these must conform to the one that came with SSDT?

when I do 'help about' in SSDT line is the correct one?

any idea what I'm doing wrong here?

Make sure if you SQL Server version is the same as Visal Studio. I use version 2019 and correct version is 150.

Just instal file: SQL2019-SSEI-Expr available on Microsoft page or other wchis is properly for your version.

Then change: "C:\Program Files (x86)\Microsoft SQL Server\150\DTS\Binn\DTExec.exe"
