Ive looked at every single solution posted about this fairly common issue but non of them work.

Also every time i download the installer non of them work to install avast.i have to always use my original installer i used the first time.

Im running win 8.1 with Premier avast

Okay, try this. If this doesn’t work let me know.

You need to repair Avast:

Start > Control Panel > Programs & Features > Uninstall a Program > select Avast and click " Uninstall/Change ". Choose " Repair " and “Continue”.

Once the repair is completed, it is essential that you reboot even if it doesn’t tell you to.

This is literally the first solution i tried.

I have also uninstalled and reinstalled many times wiped all traces of all prior antiviruses including all prior versions of avast and turned off windows firewall etc.

This should fix it. Please ensure you follow each step and do not miss any.

You need to do a clean install of avast!..

  1. Download Avastclear and the appropriate Avast edition.

Note: It’s important you used the stub online installer from the one I linked… NOT the offline one.

Note: You need to be ONLINE during this install (online installer works in all cases whereas offline sometimes doesn’t)

Avastclear : http://files.avast.com/iavs9x/avastclear.exe

  1. Uninstall Avast by control panel [If you don’t have Avast in control Panel go to #3]
  2. Uninstall in safe mode using Avastclear. [Running Avastclear is normal mode will give a prompt to go into Safe Mode]
    Check : Once uninstalled check in device manager>view>show hidden devices if there is anything related to avast with a yellow triangle… if so, uninstall it and reboot.
  3. Install the version you downloaded.
  4. Reboot.

Note : If you have a paid license, insert the license key/activation code after the reboot at stage 6.

If you have any questions, please don’t hesitate to ask.
