It happens when the Terminal Services service isn’t started, fix that.

Windows XP SP3 Terminal Services would not start - I managed to fix it by changing The Terminal Service ImagePath in the Registry Editor to :
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TermService]
ImagePath REG_EXPAND_SZ %SystemRoot%\System32\svchost -k DComLaunch

It was originally set to -k netsvcs
UI is now loading OK.

I have this exact same issue on TWO different Windows 10 Pro systems. So much so I have removed AVAST on both for the moment bexause I cannot get it to work.

I have tried both AVAST Free and my AVAST INTERNET SECURITY … I get the same issue as OP for both.

Believe me … I have tried all the usual fixes like avclear etc etc, no joy.

Any ideas … As ye know TERMINAL SERVICES is not part of Win 10. DCOM SERVER PROCESS LAUNCHER is, and thats enabled, automatic

Im wondering is it another service possibly disabled that AVAST needs? Any thoughts on that? What services need to be on?

12

What other security related services are running ???

13

NONE … I even disabled Windows own AV via GPEDIT just to see if that was the issue.

14

Sorry but I’ve never run into an install on Windows 10 were there was a problem installing Avast
unless there was a conflict with another program.
I suggest you follow the directions outlined here:

Some feedback information which may or may not help:

XP SP3. Latest Avast free version.

When I booted up today there was no problem. Avast worked fine.

I got an on-screen message from IObit Driver booster 4.4 saying something about wanna-cry. I wasn’t concerned because I had already read that Avast and most other antivirus software were now protecting against that ransomware. The message offered to check for Windows updates and Firewall problems. I checked them manually and saw no problems but I figured it wouldn’t hurt to let the IObit software run a check. It did find and install a Microsoft Windows patch. This is strange for XP. I normally only get MS Office 2007 patches. When I rebooted Avast didn’t work and I got the Avast on-screen message posted in this thread. I did a System Restore which removed the new MS patch. Avast worked properly as normal.

Hopefully this helps.

@ moznewbie

I don’t know how iObit did this update, but I have little trust of iObit software from years ago.

There was an out of support windows update for winXP, Vista and win8.0, there is a topic on the forums that mentioned this MS security update. I downloaded the one for XP SP3 and installed it and no issues with the UI loading.

I also had no problem with the UI loading on any of the avast 17.x.xxxx versions on this XP Pro SP3 system. So there to this UI not loading than it only happening with XP.

I fully share your justified lack of faith in IObit, but this is the oldest of my 2 XP machines and it was given to me 7 years ago when the screen died. It only works now on mains power and I have to use it on its side because the fan doesn’t work. I like XP and I use the other XP machine for Office and Excel. For business and ‘proper’ Internet business I use either my Windows 10 or Windows 7 machines. I have no qualms about putting this machine at risk and when it eventually succumbs to malware, ransomware, viruses, or it just burns out it can go in the skip with no hard feelings. I wouldn’t have clicked the IObit link with any of the other machines but this is pretty much a test board machine with no consequences. ;D

For what it’s worth I have 2 restore points for today. On 1 Avast worked, and on the other it didn’t. I hoped that would help but if it didn’t i’m sorry for wasting your time. For what it’s worth IObit did load an MS update that I otherwise couldn’t access. I did check it with Belarc Advisor and that update did pass a MS certificate check. I’m not 100% convinced the update was meant for this operating system and since I did the restore I haven’t been offered that on-screen link again. ???

Hi, I have the same message, UI Failed to Load, I have sent a ticket as I seem to have 2 valid licences, one for one device, and one for 3 devices. The latest licence email says it will update automatically. I have tried to install again hoping that it would just update, I have downloaded licences and activation codes but still get the same message. I seem to have paid for 2 products, but haven’t any protection, as my pc is not protected from viruses. I have not had a reply from the Avast Team, has anyone else had this problem, I’m quite annoyed as I have somehow paid twice for no protection. Unfortunately, I am not ‘techy’ so am stuck and avoiding doing certain actions on my pc for fear of hacking and viruses.
