I would do a silent installation of Jet Reports.
I downloaded the source from http://jetexpress.jetreports.com/fr/regionhome.php
I tried "Jet Express Setup.exe" / S but without success.
I recovered in temporary folders "… \ AppData \ Local \ Temp" and "C: \ ProgramData \ Package Cache" containing sources Framework 4.5, and JetSetup.exe Jet.Setup.Essentials.msi.
Do you have an idea ?
