Hi @A Ska
Sure, but first let me answer your 2 questions.
> In your XML Where is the path of the Project installation folder (I need to put it on a shared folder on a server)?
In my .xml file, I did not specific the "SourcePath", if your machines can connect to Internet, then you can install Office from Microsoft CDN (Microsoft cloud server).
But if some of your machines can not to connect to Internet, then you can download the installation package to the folder with ODT, then let these machines install Project from local source. (For details, please check the comments below.)
> Should i setup /download before installing Project?
It depends on your environment conditions.
Such as whether your machines can connected to the Internet and whether there is pressure on network bandwidth.
If Internet connection is disabled, or the network bandwidth is stressed, you can download the installation package of the Project first on one machine that can connect to Internet, copy the folder, that includes the .xml file, ODT and Office installation files to other devices that need to install the Project, or to a shared folder that the clients can access.
