Error 1721 - Basic MSI project - Silent install

Hello everyone ,

I am trying a silent install for Basic MSI project . I am running the following command for silent install .

setup.exe /s /v"/qn /l*v c:\msilog.txt"

So I am checking the log file "msilog.txt" . I found this error message :

Error 1721.There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor. Action: AddContact

AddContact is an exe file that I am calling during both silent and normal install

Note : This installation works perfectly fine in normal or UI mode . I am getting this error only during silent install


Does anyone know what this error means and how can it be resolved??? Any help is appreciated. Thanks in advance.

The problem is with your command and the quotes you are providing. can you send some more details.
use this in your script :
LaunchAppAndWait("Setup.exe" , "/s /v"/qn", LAAW_OPTION_WAIT)
