Esri Maps for Office 3.1 Silent Install broken?

[ChrisLank]

We had no trouble deploying version 3.0 of Maps for Office silently in our environment, however the exact same method fails 100% of the time when using this new 3.1 installer.  Install log throws an exit code of 1603 and we cannot determine why. Installing interactive is OK, it just appears that the silent method is broken for some reason.  We have tried on multiple systems, all had the prerequisite software and are still able to install 3.0 silently just fine.  Wondering if anyone else has run into this issue or if there is a workaround.  Thank You.

The current doc help is incorrect.

Install Esri Maps for Office—Esri Maps for Office | ArcGIS

The correct silent installation is the below.

For example,

EsriMapsForOffice_x86.exe /quiet /msicl "CONNECT_TO=http://www.arcgis.com" /msicl "FallbackToCloudResources=false" /msicl "FORCEINSTALLPREREQ=true" /msicl "CHECKFORSOFTWAREUPGRADE=true" /msicl "FORCEUSERAPPCONFIGUPDATE=false" /msicl "ESRIMAPSWEBROOT=http://la.arcgis.com" /msicl "ESRIMAPSWEBPROXY=/proxy"

The new parameters are required in the silent installation command since 3.1.

These are:

1. FallbackToCloudResurces : This is new option, which you can see "Esri Maps" Tab. When this parameter is set "true", uses can use Esri Maps with online resources if portal resources are not available and users have internet connectivity. The default is "false".
2. FORCEINSTALLPREREQ : This parameter is for installation prerequisites. If this parameter is set to "true", prerequisites are installed before installing Esri Maps for Office. if setting to "false", The installation process aborts if required software is not found. The default value is "true".

Other parameters are the same as 3.0.

The doc page will be updated soon.

Please try silent install as above.
