I need some help as I have run out of ideas on this particular problem.

Windows XP, Windows Media Edition
Build 2600 XP, SP3
Emachines Model T5048

Computer is behind a firewall, and has virus and spyware protection. Virus & Spyware is not the problem.

Installed two new programs, and then upon boot-up the computer goes into a boot loop, and will not allow boot-up under any configuration, i.e. cannot boot normally or in safe mode.

New programs installed were:
DRS2006 Cart Machine Software from

Direct Audio Center Cartwall Software from

One or both of these programs seems to have created this problem.

After looking at the files and directories in the computer, there was a Microsoft Update, KB2570791, which is a time zone update, that installed on the same date as the above software. (08/25/2011)

Here is what the computer does:

At boot, Windows XP Boot image appears, with blue scrolling status bar, and after a minute or so, the following message displays:

Winlogon.exe – Entry Point not Found
“The procedure entry point _except_handler4_common could not be located in the dynamic link library msvcrt.dll”

Then another message displays.

“User interface msgina.dll failed to load.”
“Contact your system administrator to replace the dll or restore the original dll.”

There is a restart button that appears in this second message and when the button is pressed, you end up restarting the computer and end up back to the first message, i.e. in a boot loop.

So, here is what I know so far and have done:

There were several instances found on the Internet of an _except_handler4_common error message related to msvcrt.dll, but after attempting those fixes that did relate (some did not), the problem remained.

Suggestions from the Internet found for possible fixes:
Delete dwmapi.dll from the system32 folder.
This only related to Firefox installations and this computer does not have Firefox, nor this file.

Delete mswsock.dll from the system32 folder.
This only related to a game installation, however I did rename this file to give it a test as a long-shot. It did not make a difference and I restored it.

Reinstall msvcrt.dll which may have been overwritten.
I did look at the file and it was dated 04/14/08 and the file size and date matched what should be on the computer. However, in a test I did rename the file, and then copied the file from the service pack files and tried it. It did not help the problem.

As information, the winlogon.exe and msgina.dll files are of the correct dates and file sizes.

I did contact the software suppliers, and received the following responses:

Re: DRS2006 Customer Help Desk
“I am totally sorry, but this error message is not from our software. I have no idea what causes this. It must be a problem with your Operating System”

Re: DAC Cartwall Help

“Hmmm, first time I've had this one...! A quick Google produces a wealth of
results regarding this error and the one that seemed the easiest to follow
was this one:


The DLL file is installed as part of DAC Cartwall although it would appear
that the file is installed by default on modern Windows installations (XP or
better). It's only included because Visual Studio collated a list of files
that the program uses and I thought it sensible to include them all.

There is some reference to a Registry Key being set that relates to Vista
which causes a problem on XP machines although this seems to relate to the
installation of soundcard drivers.

Sure it's not possible to press F5/F8 on startup to enter Safe Mode?
Failing that he'd have to insert his XP install CD and run the recovery
option which should restore any missing/broken files - I gather this will
keep the system intact.”

As mentioned, when I boot in Safe Mode, I receive the same messages.

The eMachines computer did not come with an XP install CD, but I did locate a Home Edition image and made a copy which at least allowed me to view the files on the computer and try some basic things with DOS commands.

From what I can gather, something is calling for _except_handler4_common which is associated with the Vista version of a program compiled probably on a Vista machine. msvcrt.dll with _except_handler4_common is apparently not found on XP.

If anyone has any ideas that could help it would be appreciated.

I downloaded the file suggested from the above link

File size: 266293
Date: 06-21-2000
The readme file with the dll file states this file is for XP/Vista.

The current msvcrt.dll file on the computer is
File size: 343040
Date: 04-13-2008
The above date corresponds to other files located in the ServicePackFiles folder.

After renaming the existing msvcrt.dll and replacing it with the one downloaded, the winlogon.exe error does not come up any more, but the computer continues in the boot loop.

It will boot to the same point where you would see the error message, and then restarts the process again, and again without stopping.

I was able to select the Safe-Mode option, and then selected Windows XP Media Center Edition, but the computer would not boot in safe mode and returned to the same boot loop mentioned earlier.

So, that did not help.

Any other suggestions?

Might be useful, http://blogs.msdn.com/b/anthonw/archive/2007/12/06/the-procedure-entry-point-except-handler4-common-could-not-be-located-in-the-dynamic-link-library-msvcrt-dll.aspx .

Generally, I would suggest running the sfc /scannow command and the chkdsk /r command...anytime that an installed program apparently gums up the works. The registry edit may work for you...but I would try the chkdsk /r and the sfc /scannow first.

As for uninstalling all traces of a program...I find that Revo Uninstaller works without a lot detailed purging of the registry by a user.

Ignore all adds, please, http://forums.whatthetech.com/index.php?showtopic=102348 .

And...if you use System Restore...that should have been the first option attempted, IMO.
