We do not support starting (like double-clicking) the MSI files directly. The MSI files require additional parameters which need to be set. We have created the SOFiSTiK Application Manager to make it easier to install and update software.

SOFiSTiK products can be installed in two different ways:

  1. You can use the SOFiSTiK Application Manager user interface to install software. This is the simplest and easiest way to install the software.

  2. Or you can use the SOFiSTiK Application Manager commandline tools to install the software. This is especially useful in automated deployment scenarios. This option provides maximum flexibility. You can even create custom mirrors of our application update content to be able to serve product updates over LAN. This is also the option which requires more initial effort.
