Bad Image error when opening .txt document

Asked By 10 points N/A Posted on -

Over the previous hours I have been trying to run every application (except IE) on my Compaq laptop and encountered this error message when I started .txt document: “NOTEPAD.EXE – Bad Image. The application of DLL c:progra~1wi930~1datamngrdatamngr.dll is not a valid windows image. Please check this against your installation diskette”. So I tried restarting my device but still getting error message pop-up and have been clicking OK to continue the boot sequence. I searched the internet and found out that these are Spyware issue. So I installed Malwarebytes and Windows Defender. I run each program but it did not resolve the issue. I also have AVG 2011 Free Edition in my device. Can somebody please help me? Thank you!

After going through your issue, I think it would have been easier to investigate your issue if you would have attached the scan results of MALWAREBYTES.( Files like: OTL.txt, aswMBR.txt).

However, based on our experience, it seems that the issue may arise when your program is calling the dll file, and could not locate the correct file OR, the dll file is corrupt or the particular dll file is simultaneously being used by another program.

What I suggest is that you try to run a diagnostic tool called : ComboFix. You can download it from :

When the tool is downloaded save it to your desktop. Disable your AVG and malwarebyte, and then double click on the tool. You have to wait for several minutes, because this tool most of the time run in background and it look like that nothing is happening, instead this tool is searching the detail programs.

After the tool has run completely , a log file will be created (C:ComboFix.txt).

Open this file in wordpad or notepad whatever is opening, and press control+F

On the pop up write: DATAMNGR, press search next.

We are sure you will notice at least two folders with something like this: (c:progra~1wi9130~1datamngriebho.dll) – File not found


Simply delete the empty folder, and your problem should be resolved.

You will need to download an application called ComboFix, and you can get one from Bleepingcomputer, or

Combofix is a malware removal tool as well, and then you will place it on your Desktop after it has finished downloading.

You will have to make sure that you have disabled all antivirus and any anti malware programs that you installed on your computer; otherwise they may end up interfering with the installation of ComboFix application.

You may find that the ComboFix application may be slow when it just starts, and it may also appear to be doing nothing before it starts scanning, but do not worry about that, you will need just to leave it and it will star for sure.

There is one thing that you should note though, that you can never use this program to remove files, for it can damage your computer.

In my experience, you only get “Bad Image” when running incompatible programs. These are the programs that managed to install on your computer though they are not compatible with the platform. Normally, when you install a program, the application should be able to identify if the target platform is compatible. If the target operating system is not supported, it should display an error message then stopping the installation.

But in this case, the error is triggered when you start Microsoft Notepad which supposedly shouldn’t happen because the program is part of the operating system. If you suspect that a virus is doing this, download Sophos Virus Removal Tool and install it. Once installed, start Sophos then wait for the virus signature database to get updated. When updating is complete, click to start scanning your machine.

When a virus is found at the end of the scan, remove or delete it then repeat the scan over and over until it no longer detects a virus. On the other hand, if no virus was found and the system turned out clean, it could be a problem with the system itself.

Try using the System File Checker utility to check the operating system’s protected system files for errors. Press the Windows key + R to bring up the “Run” dialog then type without quotes “cmd” then hit Enter. In the command prompt window, type without quotes “sfc /scannow” then hit Enter. Insert your Windows setup CD or DVD when you are prompted then continue.

Wait until the process is complete. When it is finished, close the command prompt then restart the computer. See if this works. Also, please remember: you can’t use or install more than one antivirus on your computer. If you have Malwarebytes, don’t install another one like AVG. Select which of the two you are going to use then uninstall the other one.

If you have Windows Defender, it’s fine. Windows Defender disables itself once you install a third-party antivirus.
