A restart should always be done after a program update and we (on the forums) tend to suggest a reboot after an Avast Repair.

thanks for your help thus far.  I did a restart and it hung up for about 15 mins   so I powered down then started, went to add/remove, brought avast and clicked change... modified then it asked for a restart.........that restart went smoothly about 4 minutes total   BUT still same ol thing    I rt clicked on a picture and chose scan....... an error box came up and said
AVASTUI.exe is currently not running, please run the application before starting a scan
it's like I have it but, I don't    in search for AVASTUI.exe comes up no results

Do you see the Avast Tray icon to the bottom right of the XP screen ?
See attached image of mine on an XP Pro SP3 system.

Do you have your desktop icons displayed, I normally don't, but there should an avast desktop icon.  That should launch the avastUI.exe, assuming that you do have it.  It should be here C:\Program Files\AVAST Software\Avast\AvastUI.exe.

I ran services.msc and the two you mentioned were set to manual........I changed to automatic and did restart
 still no avast UI    after reboot I went back to services and the two were on automatic startup
I saw AVAST in services and clicked on it and saw that it was stopped   so I clicked for it to start...   a windows progress bar came up like it was loading      Then I got a windows error 1053 or 1503 that the application would not respond in timely matter
still no avastUI or any kind of AV service

unlike the OP, i'm on xp sp2 [not sp3] and hence avast 10 [not 18] but having similar issues since rebooting after an update which may have been installed weeks ago since i use standby.
this seems wide spread, so i joined just to share my fix [took me days] which should work on
xp sp3/v18 too.

need [A or B]:
A] old avast offline installer
 or
B] use system restore/recovery image backup to extract old avastUI.exe before this update bug occurred [why it even gets updated on just a database update with no program update is beyond me]

steps for A]
1.install old avast version
2.backup avastUI.exe from programs folder [incase it gets updated in step 5-6]
3.do a manual database update or download/install it from:
https://www.avast.com/en-au/download-update
[untill this is fixed, steps 2-6 is how you will update from now on]
4.also turn auto updates OFF or it will freeze again after update/reboot!!!
5.reboot to safemode [to stop avastUI.exe from being updated]
6.reboot in normal mode: sweet - it works again! -if not go to steps 1-2 below.

steps for B]
1.extract old avastUI.exe from programs folder [compare version number to updated one]
2.reboot to safemode and overwrite newer avastUI.exe in programs folder with the old extracted one
3. do steps 4 & 6 above
4. for future updates, do steps 2-6 above
5. ....um, that's it i think? if any of this stuffs your pc it's not my fault!   ???:o ::) :P 8)

@avastui bug.
Without a link to that older version, your help isn't much good.
Title: Re: avast free failure to launch
Post by: REDACTED on September 26, 2018, 05:43:50 AM
avast does not store old versions publicly that i know of, any link would be unofficial and possibly insecure, it's the users responsibility to make archives of software they use in case things like this ever happen, if not, an old pc magazine dvd from a library might be another option.

...besides, option B does not even require the older installer   :P

...just a heads up for anyone trying my fix above, you also need to block 'AvastEmUpdate.exe' in your firewall or it will still update a few days later even with auto updates off!
Title: Re: avast free failure to launch
Post by: mchain on September 28, 2018, 07:06:15 AM
Note:  Blocking AvastEmUpdate.exe is not recommended as it is needed to fix issues with an avast installation behind the scenes.
Title: Re: avast free failure to launch
Post by: REDACTED on September 28, 2018, 02:20:25 PM
fix issues? in this case it CAUSES the issues, all it does obviously is download/install updates, which can be done manually when needed as i described.

also note this thread is about win XP, other versions may not have the issue.

It (AvEmUpdate.exe) isn't causing any issues on this XP Pro SP3 system with the latest avast avast free version, see attached image.

I also have Program Updates set to Manual and the AvEmUpdate.exe is still enabled, it has never automatically done a program update.

One use for AvastEmUpdate is to fix a false positive detection causing many systems (home/business) to crash, with blue/screens, which does happen but rarely.   ::)

IMO turning off AvastEmUpdate is not something one should do.

When running an Old XP with SP2 it will be increasingly difficult to secure the system effectively with many Security Programs.

It's nice to offer help but, that help needs to actually be complete.
Suggesting the disabling of functions that need to be there isn't helping anyone.
Asking people to download older versions without supplying a safe link also isn't helpful.

if you read my post, avastUI.exe bug is not caused by program updates, but by database updates - strange huh?

1] It's nice to offer help but, that help needs to actually be complete.
2] Suggesting the disabling of functions that need to be there isn't helping anyone.
3] Asking people to download older versions without supplying a safe link also isn't helpful.
1] it's the only viable [and working] solution so far, so unless you or avast have a better one your comments are even less helpful.  :-X

2] the function is invalid if manual updates and maintenance are performed [such as when avast gets compromised by an attack]

3] i never once asked people to 'download older versions' as anyone still using XP should be keeping copies of old software that gets discontinued and unavailable frequently, those who don't should chuck their XP pc and buy win10 like everyone else who can't maintain old OS's confidently.

<snip quote>
I did, I also read your other posts that imply a problem with AvEmUpdate.exe.

I'm reporting the condition and settings on my XP system and the fact that I haven't experienced the problem.  The major difference that I'm not using XP SP2 but SP3, Avast should detect that and not update the program to a version that requires XP SP3.  Why you haven't updated your OS to SP3 is the question.
Title: Re: avast free failure to launch
Post by: REDACTED on September 29, 2018, 10:43:42 AM
sp3 slows my system if it's an upgrade install, a fresh sp3 slipstream install is not viable to me yet.

the OP also has sp3 and the same problems, so why him and not you? maybe he did an upgrade install so still has legacy sp2 files, or maybe as we use xp home while you have pro?

non SSE2? my XP pc may be old but not THAT old, my cpu has that, and also SSE3/SSSE3 & SSE4.1.

i'll also pass on the dodgy non-official avast 10.4 download even though it's newer than my archive  - but thanks for sharing anyway!  ;)
Title: Re: avast free failure to launch
Post by: REDACTED on October 01, 2018, 07:33:19 AM
my curiosity got the best of me, and i tried v10.4 in a VM - does not have the UI bug so can auto update and don't need to block avastEMupdate, so thankyou very much bob - now my avast can be 3yrs old instead of 4! ;D

but after all that, i actually found an official link to v10.2 here: https://forum.avast.com/index.php?topic=222254.0

You just download and run the programs and they will create some logs

just as easy as downloading and installing avast ... well in your case easier   ;D
