Installing avast

I can’t understand why Avast Home Premium setupengpro can not run on my system. Please I need help as I have the Licence Key with me.

Is this free or pro…??
You give conflicting info…

What is “Avast Home Premium”? Don’t know any product of that name…

As has been said there is no such avast! Home Premium application. The old avast! Home name was used in version 4.x and was free, there was no Premium (paid) version.

You mention setupengpro, which relates to avast! Pro and an old version at that, now the avast! pro installation file is setup_av_pro.exe

Where did you download this from and where did you purchase the license ?
Exactly what version did you download and get a license for ?
