Avast installing utility running but nothing really install

[system]

Hello,
So I wanted to give a try to avast premier pro. But if I have the widget at bottom of computer running and saying it is installing. At the end of the progress bar (which went pretty fast for a avast installation) nothing happens. No avast.
So I made some researches on my computer and on my program list Avast is there but doesn’t have its icon just like a random program. Also there is nothing in C:\Program Files (x86).
I don’t know how to solve this problem I tried to totally uninstall avast then reinstall it, repair with the uninstaller utility, delete all avast files (even the ones with trusted installer) but nothing has fixed my issue…

If anyone know what is the origin of the problem I’m facing thank you in advance.

Have you removed previous used antivirus according to vendors instructions / removal tool ?

Yes I have. That’s what’s weird I’ve made a very clean install… Totally remove Bitdefender that I previously had.

As I said earlier I totally uninstalled any other antivirus software on my computer.

Did you get your copy from here and did you use the offline installer? https://forum.avast.com/index.php?topic=219889.0

Online installer can/does have issues dropping out at parts of the install process.

I’ve installed Avast thanks to your links but now I get an application error relative to AvastUI.exe which can’t launch. This error made hardcrash my computer by the way…

Perhaps you got your avast copy elsewhere? And was Premier Pro a fully licensed copy or a trial version only? If you got your copy elsewhere please provide a link to it.

I did not, I followed what you said. And got Avast versions only from trusted and official sources. It was supposed to be a trial version
