It's possible to install IntelliJ IDEA based IDEs silently on Windows. We are using NSIS installer and it accepts the following command line switches:
- /S — perform silent (unattended) installation into the default installation directory (the switch is case sensitive)
- /D=<installation directory> — change the default installation directory
ideaIU-15.0.3 /S /D=W:\Program Files\IntelliJ IDEA 15
You can find more details in NSIS documentation.
At the moment we do not provide MSI installers for our products, however you can create your own MSI package by wrapping our installation executable inside MSI in the silent mode.
