APPCRASH with MSVCR100.dll

[Thorgils]

This seems to be a common problem here, but I also see admonitions against following advice given to other users;  rather, we're urged to contact support with our own particulars, so here goes.

 

1)  When I started to use my long-installed MBAM free version this morning, I was able to update the database without problem.  I was then prompted to update the software, which I did.  I crashed when trying to open the application.  I retried, and this time the application opened but crashed when asked to run a scan; this ("crash on initiating a scan") has been the pattern for all subsequent attempts.

 

2)  I followed the instructions for "MBAM Clean" to the letter, and reinstalled a new copy.

 

3)  My most recent diagnostics are as below:

 

Problem signature:
  Problem Event Name:    APPCRASH
  Application Name:    mbam.exe
  Application Version:    1.0.0.532

  Additional Information 3:    2e01
  Additional Information 4:    2e01b10c887fd7f971b05773252074ee

 

I note that this log shows the MBAM version number as 1.0.0.532, whereas the installed software is V. 2.0.2.1012.

 

I'm running under Win7x64 SP1, and have never had any previous issues with MBAM.  I'd be grateful for any help in resolving this.

Hello and welcome aboard.

 

{minor point:  The version number as 1.0.0.532 listed in the report is about mbam.exe file and not referring to the "Anti-Malware program" version.}

 

This tool will collect some information on the installation of Malwarebytes and create a report I need to review:
Download mbam-check.exe and save it to your desktop    from  http://downloads.malwarebytes.org/file/mbam_check
On Vista/Windows 7, 8, Right-click on mbam-check.exe & select Run as Administrator & allow to Run.
On XP,Double-click on mbam-check.exe to run it.
It should then open a log file CheckResults.txt
You should attach the CheckResults.txt file located on your desktop so that I can review.

 

Thanks.

Here you go.

CheckResults.txt

[Thorgils]

Whoops, I failed to "run as administrator" the first time.  In case it's different, here's the result from running as administrator.

Hello Thorgils,

 

You need to do a full removal and then a brand new install of the Anti-Malware.

 

Go to Control Panel >>All Control Panel items >> Programs and Features.     { on XP you use Add-or-Remove programs }
Locate and select **Malwarebytes Anti-Malware** and  (( if not there then skip this part ))   do a Right click on it and select Uninstall.
Allow the Uninstall to proceed.
Close Control Panel when done.

If the uninstall from Control Panel hiccups or does not work, please go forward and use the mbam-clean step  anyway.



Close all opened windows/apps so you will have a clear view to the desktop.
I would suggest, a new clean install as follows:
Download and SAVE  mbam-clean utility from  http://downloads.malwarebytes.org/file/mbam_clean

then run mbam-clean.exe:   Double click the "mbam-clean-2.0.2.0.exe" file to run the clean tool. It runs quickly.

It will ask to restart your computer, please allow it to do so very important



Next Download & SAVE  the latest version of Malwarebytes' Anti-Malware from
http://downloads.malwarebytes.org/file/mbam

Run the mbam-setup.  IF your Windows is Vista / Windows 7 / 8, then do a Right-click on **mbam-setup.exe** and select Run as Administrator and allow to run.
Then after the setup has finished, on the Dashboard screen, press the **Update now** link.
Let me know if the update succeeds.

When all done, do a new (fresh) Windows Restart.

Hello Mr Naggar,

Per my original post, I had already tried a clean and reinstall, following the "MBAM Clean" instructions.  But I had not run the programs "as administrator," so I followed your instructions here (and additionally turned off my antivirus (Norton 360) as I reinstalled).  The reinstalled MBAM still crashes on attempting both to update the database and to initiate a scan.  I'm attaching the log file from attempting to run a scan.

The abend should be just a temporary one-off glitch.

 

First, ( but only if the program is running) lets shutdown the realtime Malwarebytes Anti-Malware. Go to the desktop Taskbar. See the blue-color MBAM icon in the notification area.   IF not there, ignore this part.
Do a Right-click on it with your mouse, and select EXIT.

 

 

 

I have attached a zip file which you need to Save to your system.

Once saved, unzip it to extract all contents.   which will be 2 files.
Next, double-click on **net_replacement.bat** file.
It should run fairly quickly in a command-prompt window.

Once that is done, restart the Anti-Malware and let me know if it works normally.

Netconf-batch-file.zip

[Thorgils]

The net_replacement routine appears to have solved the problem -- the database updated without a problem, and the scan is now running normally.  Many thanks for your help with that.

 

So what was the problem there, and how does it arise?  Are there any implications for future MBAM updates, or other software installs?

[Maurice Naggar]

Very good, then.

It is truly not possible to guesstimate the exact reason this occurred on your system.

This should be a one-off occurrence.   I fully expect you wont have it again on this system.

There is no implication for other software.

 

You should delete the "mbam-clean-2.0.2.0.exe"  + mbam-check.exe

FWIW, I created a MB account just to say I had this exact same problem on a Windows 7 x64 machine and this batch file fixed the problem.
