Post back on the forum if that takes care of the problem or not.
It could help others.
Clean install worked like a champ! Thanks!
Followed your instructions using the offline download after a control panel uninstall and avastclear and still have the same problem, “UI failed to load…”. Any other recommendations?
bob3160 I did a clean install of ver 191.4142.424 About 5 hours later avast shut down for about three minutes and wouldn’t restart and then it did a automatic program “update” and it is now ver 191.2360 It DOWNDATED instead of updating, it went backwards on versions. Then about five minutes later it shut down for a minute and then restarted by itself.
19.1.2360 is the latest version, don’t worry about 19.1.4140.x which is not a version number but a build number
The update I installed today also broke my installation…
There’s multiple reports of this here today.
Time to cease distribution of this update and wake up the engineers!
Hi all, I’m trying to induce it: Avast free 18.8 installed and updated to 19.1, but UI works fine. Can anyone please collect logs: c:\ProgramData\AVAST Software\Avast\log\ and send them to me ( petr.blatny@avast.com ). Thank you very much
I don’t know how, but yesterday the problem was suddenly fixed by itself. UI has been working fine since.
this morning when I booted up the computer the UI Failed to load again so I did a repair. 5 minutes after the repair completed avast shut down again and the UI Failed to load again. So I am back where I started from not only with the UI failing to load at boot except now it’s even worse since the update about five days ago avast is constantly shutting down and then failing to restart again over and over and over as many as six or more times a day.
Avast has a built-in program called AvastEmUpdate.exe which runs at every system boot and automatically fixes Avast related bugs or glitches. Which is why one sometimes needs to boot more than one time while connected to the internet. A second reboot while connected usually sets the fix in place.
A standard practice I use is to do a clean install anytime the Avast version number goes up by one, e.g., from version 18 to 19, using bob3160’s clean install method.

Too many changes are made in the course of updating version 18 during the time it is supported for bug removal and glitches. Version 19 is also an upgrade in protection abilities to protect against new malware, which is why it is being introduced vs. 18, but some old 18 files and registry entries can remain and affect proper operation of 19. These duplicate files from version 18 and then 19 are not meant to remain but it does happen. A clean install reduces the chances of a botched install of the new.
Some old files are not overwritten and replaced as they should be in an upgrade, as it were.
I always use the offline installer. I’ve found to be more reliable and it works better than the online installer. Plus, if I save the offline installer in a safe place, I can always safely revert to it in case the newer version fails to work out properly.
Online installers don’t offer that option.
I’d offer one caveat to the Off Line Installer.
If you’re using Windows XP or Vista, use the online installer so you only receive the version
that works on those systems. The latest version doesn’t work on the older systems.
mchain avast demanded a computer restart two or three times yesterday and then I shut it down last night and started the computer again this morning and after all that Avast kept shutting down and restarting over and over again today and each time the UI failed to load again. I never had any of these UI Failed to load problems until version 18. And I never had any of this mess with Avast shutting down and restarting itself let alone six or more times a day until version 19. Up until now I have never had to restart the computer after a new version was updated, this is the first time I was confronted by Avast demanding a computer restart. I have installed an older version and turned updates from automatic to manual and I will leave it like that for a while and hope that in a month or so Avast will get thees software glitches removed from the newer versions. This is nothing but glitches in the new versions.
Catrike, see Reply #110 on: Today at 03:42:56 PM in the pinned post “New Version: 19.1.2360” with new info from the product manager on the problem we are having. Hope it works or I am going to start looking elsewhere.

mchain I see MartinZ says in that post there is supposed to be a fix by the end of the week for the UI Failded to Load problem. In the mean time I have ver 17,5.3585.0 installed and neither of those bugs are in it and it is functioning with zero problems. It has been so nice: The past two mornings Avast has loaded without a UI Failed to Load box popping up which it has done every single day since the ver 18 updates. And also no more of that crap of Avast shutting down by itself over and over six or more times a day every day since the ver 19 updates. I have the Program Updates set to Manual and that is were it is going to stay until the programmers at Avast can get their act together and get these bugs out of the new versions of the software
A Japanese user also reported the same issue.
Is the patch already released, or still need investigation?
@petr blatny
Do you still need logs? I can ask him/her for logs
Does anyone know if the fix for this problem, that MartinZ said in his post located in “New Version: 19.1.2360” would be available the week ending on Jan 12, has ever been applied. I have not seen anything ever mentioned that it has been resolved.
I still have the “UI failed to Load” problem, and it’s Jan 30, 2019. I just restarted my machine (using Windows 7). not happy. Also, what the heck is “UI”?
“UI” = User Interface. It’s the program window you interact with to perform certain functions or call up certain features or operations within the program. Otherwise known as “GUI” Graphic User Interface.
