P3Dv4 747 QOTSII install - disable Avast!

Recommended Posts


Just a tip for anyone struggling with the new Prepar3dv4 compatible 747 QOTS II  installer seeming to just shutdown with no error and then the installation exe disappearing, for me it was actually Avast, and disabling all shields for 10 minutes let the installer complete successfully.

I realise the fleet Captain probably said very clearly to disable anti-virus when installing, but it didn't stop me not following instructions, so maybe this will help someone equally nonobservant :D
