Title: avastui.exe application failed to start
Post by: Tatsu333 on February 19, 2010, 10:38:57 PM: After numerous tries to install Avast 5 on a Dell laptop running Windows XP SP3, I have not been able to get around this. The installation appears to go through fine, but I am not prompted to reboot after. When I try to launch the Avast application (either from the desktop or Start menu), I get an error saying that the avastui.exe application failed to start because the application configuration is incorrect.

I have gone through removing and reinstalling numerous times, both from Safe Mode and not, using the aswclear5 utility and not, but no luck. Any ideas?

I should note that the services do appear to be running just fine, I just can't launch the UI.

Try.

Any other antivirus before avast? How it was uninstalled?

Post by: pido on February 21, 2010, 05:54:02 PM: Hi,

I got the same issue.
OS: Vista 64bit Home
I upgraded from avast 4 home edition to avast 5 free edition following the steps provided.
AvastSvc is running, though I don't see any avast logo in the systray.
I rebooted, uninstalled, reinstalled, rebooted etc but the failure is persistent.
Seems like a bug to me.

Regards

Title: Re: avastui.exe application failed to start
Post by: Sebastian09 on March 01, 2010, 04:00:00 AM: I ran into the same problem with an Acer laptop with WinXP SP3 that had previously had older Avast versions installed. I removed and installed the latest free version three times and every time I get the same error:

"C:\Program Files\Alwil Software\Avast5\AvastUI.exe
This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem."

This is very frustrating and I hope somebody can help. In light of this help I definitely won't try to buy a better version...

Post by: olddog on March 01, 2010, 05:08:56 AM: Tatsu333, Sebastian09 and perhaps pido,

"This application has failed to start because the application configuration is incorrect" and "side by side" errors have been reported a number of times in the forum. I don't know whether this is applicable in your cases or not, but from memory Avast was not able to find the correct version of Microsofts Visual C++ run time library. I seem to recall a post indicating that the correct version was provided as part of the Avast installation, so it may be a case of determining whether it did not get installed for some reason.

Post by: pido on March 02, 2010, 07:17:31 PM: Hey olddog,

It seems like your the only one that pays attention to this problem, thanx.
If been searching my registry for clues on your tip.
Strange things I found:
ImagePath=\??\C:\Windows\system32\drivers\aswMonFlt.sys
DataFolder=\DosDevices\C:\ProgramData\Alwil Software\Avast5 (I got more of those prefixes)

I couldn't find any Avast key referring to any C++ runtime.
Can you give a hint?

C++ runtime should be installed in windows\winSxS directory during avast5 install. Probably you have troubles with this store. E.g. diagnosing SideBySide failures is described in http://blogs.msdn.com/junfeng/archive/2006/04/14/576314.aspx

Post by: pido on March 05, 2010, 07:24:32 PM: Update:

So I checked the winsxs folder and there's lots of stuf there.
I also ran sxstrace but that resulted in a binary file that couldn't be parsed.

I used to be happy about avast but this going more-commercial and leave the home edition for rubbish.
Really make's me wonder

Since Avast has decreased it's protection through webpages (excluding Sandbox) and this problem isn't solved yet, I think I'm going for the alternative: Avira

Post by: Exciter on March 11, 2010, 05:51:37 AM: I have been having a hell of a time with this..
I tried installing net framework 3.5 and the 2008 redistribute.
Nothing worked.

However I did manage a work around by searching for vc90.crt on another xp computer. There were about 8 files in the windows\winSxS directory that I copied over to the problem computer.
Then the event log showed a side by side error for vc90.mfc.
I did the same thing, searched for vc90.mfc and found about 8 files again.. Copied to the problem computer and boom. Avast started up.

Hope this helps someone else.

Post by: pido on March 14, 2010, 01:29:56 PM: Does anybody know how to fix WinSxs.
Avast totally messed up my computer with this.
Update nor other programs that require winsxs all fail.
This is like a nightmare and Avast isn't providing support.

Post by: mikemason on May 17, 2010, 08:30:18 PM: Yea there is a way to fix all that avast ui.exe stuff. forget all that 3.5 framework if MS want let it install and google Microsoft visual c++2010 express (it is free) make sure to download all especially the VC 9.0 runtime and there you will see a 4 net framework you will need and other software but you can probably opt out of silverlight or go ahead and the disable what you don't need. There are about 9 parts to this download so be patient but when you are through make sure all previous av software is uninstalled and the install avast 5 and presto ui works and then you will see the orange avast ball in status bar. NOTE THIS DOWNLOAD WILL TAKE QUITE A BIT OF TIME.
