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.
use this in your script :
LaunchAppAndWait("Setup.exe" , "/s /v"/qn", LAAW_OPTION_WAIT)
Note : I am gettin 1721 error only for silent install
