Silva was signed from Porto for £34m by Milan, who are competing in Europe for the first time in four years.
The Italians spent around £170m in the summer and new recruit Hakan Calhanoglu put them ahead with a thumping drive. Ex-Liverpool player Suso netted the fifth after Silva's treble.
Defender Alexandar Borkovic powerfully headed in from a corner for Vienna.
Turkish midfielder Calhanoglu - bought for £22m from Bundesliga side Bayer Leverkusen - ran the game for Vincenzo Montella's side, providing two assists in addition to his goal.
