Pascal Vaudequin's side came from a goal behind to win

Barry Meehan controlled a cross and fired the ball past Alan Ryan on two minutes and then almost got a second.

Tommy McCallion and Kevin Ramsey went close for Institute before David Ogilby equalised with a 25-yard left-foot effort from a free-kick on 71 minutes.

Ten minutes later McCallion shot home into the bottom corner with a beautiful right foot shot from Ruairi Boyle's cross to give Institute the points.

Armagh's best chance of the second half fell to goalscorer Meehan but he was unable to convert.
