Title: Avast Free installer problem.
Post by: schteeb on May 05, 2014, 07:40:23 PM

I installed Avast free a week ago and today the error, HTMLayout.dll cannot be loaded to properly start the GUI. Therefore the process cannot continue.

I tried searching and downloading the HTMLayout.dll into the system folder but that didnt work, so I uninstalled avast fully with avastclear... now im trying to install avast again but its still giving me the same error even though i fully uninstalled avast...

I am running windows 8.1 64 bit.

First make sure there are no remnants of a previously install av other than avast.

1. Download Avastclear, Rejzors uninstall tool and the appropriate Avast program edition.
Here are the installer links. Note: You need to be ONLINE during this install.

2. Uninstall Avast by control panel  [If you don't have Avast in control Panel go to #4]
3. Uninstall in Safe Mode using Avastclear.

4. Run Rejzors Uninstall Utility in Normal Mode (removes traces avastclear doesn't) - reboot.

6. Install the version you downloaded.
7. Reboot.

Thank You Eddy.

The uninstall went perfectly with both programs used as you directed. The ck of the Device manager shows nothing more of the Avast program. I downloaded another copy of the avast premier...and when I attempt to (re)install I still get the same error message.

Making progress but still not quite there.......
