Errors. Sometimes they just seem like a way of life when you’re working online. If you’re suddenly seeing a datamngr.dll, don’t panic – this problem isn’t as terrible as it may seem. And (for once) you’re not actually dealing with malware or a virus. This is just a problem with your computer making the right connections.

What Is a Datamngr.dll?

A dll file, or dynamic-link library, is an executable file that helps to support an application. We actually need these little guys to make the various programs we use on a daily basis function seamlessly. A datamngr.dll is just one of many .dll files that can cause problems if things don’t correct properly when a file is installed or uninstalled. Often, removing a file can leave these little executables behind causing the sorts of errors that are giving you a headache now.

The technical?  Specifically datamngr.dll is a data access layer component, a fundamental resource that helps different programs (as the name suggests) manage data.  This management comes in the form of creating files, reading them, updating them and deleting them.  You can tell right off the bat that it’s important, so getting a problem means that there’s some factor blocking a given program from controlling its data.

Resolving a Datamngr.dll Error

If you were to look around online to find a solution to the datamngr.dll error, you’d likely start to panic. There are many websites promoting malware software to remove this “dangerous” error. Unfortunately for these websites, you’re not dealing with anything dangerous, and you’re not likely to fall for a shady company trying to make you download something to “Fix the Datamngr.dll Error Right Now!” After all, you can certainly do this yourself.

Be safe when you're searching the web.  Remember that lots of vendors key in on a given name and try to scare you into thinking it's malware.  It's true that malcious software can imitate Datamngr.dll, but usually the cause of the error is more direct.  If your computer is acting odd in ways that don't seem to be related to the conditions outlined above; be suspecious.  If it's not just a recurrent error with one or more programs but systemic slowdown, popus, browser hijacks or computer crashes - then you might be dealing with foul play.

Otherwise, it's a documented and fixable problem - one that anyone can certainly handle.

If you really feel you must have support as you work through these steps, there are programs that can help you clean up your machine and resolve the error in the process. Just be sure to download programs from a company that you’ve researched and found reputable. It makes no sense at all to download malware to defeat something that isn’t malware.

Instead of looking for a quick fix provided by a company, perform your own quick fix. There are several things you can try to beat this error – some less complicated than others.

How often have you gone to pull up your internet only to encounter an error? If you’ve run into an error called xpcom.dll, you were likely working in Mozilla Firefox or perhaps Thunderbird and then your program unceremoniously shut down on you. While kicking or punching the computer might be considerably more satisfying in the moment, it would make far better sense to just handle the problem – the DLL for Mozilla isn’t working correctly.

What is XPCOM.dll?

DLL files are the files necessary to make program work. The DLL works behind the scenes to ensure everything is working smoothly, but sometimes the DLL file is corrupted on start-up or has an internal glitch that causes it to stop working correctly. When the DLL file goes bad, the whole program can go bad. You might start seeing error messages or you might find yourself looking at a frozen screen. That’s if you’re able to get Firefox to open at all.

Fortunately, as frustrating as a XPCOM.dll error can be, it has a simple solution – you just need to remove the corrupted file and reload the correct one so that all of your programs can work normally again.

Method 1: Updating Firefox

What Version Do I Have?

Often the DLL errors that occur in Firefox can be resolved by simply updating the software. If you can open Firefox, you can check if you’re using the latest version by clicking on the Firefox button in the top left corner of the screen. From there, click on Help and then About Firefox.

How often have you opened up your Internet Explorer only to have it crash, close and give you one of the cryptic messages about reporting the error? You’re likely not very interested in reporting an error – you’d rather get your internet up and working again. If you’ve examined the logs of the crash, you can see all sort of gibberish, but look for an indication that it is the “yt.dll” causing the problem. If so, the problem is simple – your Yahoo toolbar is messing up and needs to be fixed.

The YT.dll.err

Computer errors are unbelievably frustrating, but when you can actually fix the problem yourself with minimum amounts of trouble, you’ll feel great and be back to work in no time. In this case, the closing internet explorer window or the cryptic warning messages you’ve been seeing are a sign that it’s time to rework your Yahoo toolbar. You’ll want to start by confirming that it is the Yahoo toolbar giving you trouble.

In the error logs, you’ll know if it’s the Yahoo toolbar by the name of the DLL file associated with it. YT.dll is one of the major support files for the toolbar. If it becomes corrupted or doesn’t work properly, your toolbar won’t work properly.  Never fear, however, it’s simple to resolve this particular problem. You just need to uninstall the Yahoo Toolbar and then reload it so that it’s working correctly again.

Repairing/Removing the Yahoo! Toolbar

To remove the Yahoo Toolbar, you’ll start by going to Start and then Control Panel. From there, click on Add and Remove Programs. In the newest versions of Windows, you’ll go to Programs and Features from the Control Panel.

DLLs are little executable files that contain data that multiple programs can use at once. This saves space on your hard drive because not every program needs to take up space with the same code. Generally, DLLs are very helpful when it comes to the functionality of your PC. However, they can also be used for evil. Gasp!

Some types of spyware use DLLs to do their dirty work, infecting your PC with bad stuff. And with DLLs, you can’t just delete them. They must be deleted and disabled in your system before they are gone for good. So how do we do that?

Safety First

You may have pinpointed the bad DLL that is messing up your system. However, you should still take precautionary measures before disabling and deleting them
Precautionary measures equal: backing up your files (like you’re supposed to do regularly anyway) and creating a System Restore Point. In order to create a point that you can return your system to in case of catastrophe:

1. Click on your Start button and go to All Programs.
2. Open Accessories and then System Tools.
3. Click on System Restore and follow the onscreen instructions.

Step 1: Finding a DLL

The first step to disabling a DLL is to do a search for it on your PC and find the exact path of the DLL.

1. Go to your Start menu and click on Search. In Windows Vista and Windows 7, you can just search from the Start-Menu's Search Field
