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.
