I work in higher ed IT and got bitten hard by the “Installation failed” bug while trying to install the CC 2017 Master Collection in a lab setting earlier this week.

Oddly, the very same installer (enterprise build) worked the week before. A fresh and updated rebuild did not help.

At any rate, we corresponded with Adobe and they have been deluged with complaints. They identified 2 of the apps that were causing the issue (Scout and one other odd thing I don’t recall ever hearing about before).

A fix is expected Monday (2/27).
