How do you install in this mode?
avast doesn’t have a compatibility mode.
What exactly is it you mean ?
Gator71 if you mean by the system requirements for Avast. Please read the following link https://www.avast.com/faq.php?article=AVKB44
Avast works on both 32 and 64 bit systems and comparability mode isn’t required to run Avast.
I saw it on a forum…
From what the thread says, Avast can run alongside another AV in compatibility mode???
