Avast installation trouble - UI Failed to load

system · 2017-07-03T20:26:07.000Z

Hi,
I have touble with installation of avast. After last avast update it shows window with “UI Failed to load. This is really embrrassing. AV Service is not responding.”
So, I try to repair (same result), uninstall & clean with avastclean.exe & delete programfiles\avast software* & programdata\avast software* & reboot and still problem persists.

It it avast Free on 32bit Windows 10 Home with Creators Update (version 1703, up-to-date)

It looks like a compatibility problem to me, but only windows defender is installed (within windows) and I disable WD through registry and it did not help.
No other AV or security software installed on the computer.

Perform a true clean installation of the latest avast version

Remove everything from installed or previous installed av’s
Remove everything from avast
Check manually for leftovers (folders, files, registry entries) and if found remove them
Reboot
Try to install the latest avast version

thanks for the quick reply, I have tried uninst avast (computer uses only avast more than 4 years), delete folders mentioned above.
reboot. install avast directly from avast.com

I have no other ideas, how to solve it

Removing the folders/files is not enough for a real clean installation.
