If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.

As you know, DLL files in the Windows environment contain all the code needed by programs in order to properly function. And like with most other software, the functions in the DLL file have to be compatible with Windows especially if they are using any built-in service. So if you encounter an error that says, “DLL is either not designed to run on Windows or it contains an error”, when you try to launch a program, then this could be due to a compatibility issue. To fix this error, read on as this post will walk you through doing that. Based on the reports of users who encountered this error, the error pointed to a DLL file that was either designed to run on a different version of Windows. It is also possible that the DLL file itself is the problem. Here’s the complete error message:

“Bad Image – DLL file is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.”

According to security experts, the DLL files that are known to trigger this kind of error message are msvcr100.dll, msvcr110.dll, msvcp140.dll, lmirfsclientnp.dll, and so on. To fix this problem, you can try to update or reinstall the program that’s throwing the error to its latest version. You could also ask the vendor for the latest version of the DLL as well as run a System File Checker scan.

Option 1 – Try to update or reinstall the program to its latest version

The first thing you can do to fix the problem is to update or reinstall the program that’s throwing the error. It is possible that the version of DLL might be using a system call that is deprecated. So if you had updated your Windows 10 computer recently, you might want to check for an update of the software or you could also try to reinstall its latest version.

Option 2 – Try asking the vendor for the latest version of the DLL

The next thing you can do to fix the error is to ask for the latest version of DLL from the vendor. There are times when the software uses an open-source version of DLL so it is better if you ask the vendor if there is a DLL file that has to be updated. If there is, then you need to make sure to register the DLL once you have it.

Option 3 – Try to re-register the problematic DLL file

You can also try to re-register the DLL to resolve the problem. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) controls in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
  • exe /[DLL file]
  • exe [DLL file]

Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.

• After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 4 – Try to replace the DLL file from a trusted source

• First, you need to get the new DLL file from another computer with preferably the same file version number.
• After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
  • x86: This PC > C:/Windows/System32
  • x64: This PC > C:/Windows/SysWOW64
• Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
• Now type the “regsvr32 ntdll.dll” command and hit Enter.
• Restart your PC and check if the error is now fixed.

Option 5 – Run System File Checker scan

If reinstalling the program didn’t work, you can also try running the System File Checker or SFC scan to fix the error. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Hit the Win + R keys to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

 Reboot your computer.

Option 6 – Troubleshoot the isDone.dll error in a Clean Boot State

You can also troubleshoot the “DLL is either not designed to run on Windows or it contains an error” in a Clean Boot state. It could be that there are some third-party applications in your computer that are preventing the application from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After you’ve set your computer into a Clean Boot State, make sure that you’re signed in as administrator and then try to install the application again.

Option 7 – Try scanning your computer using Windows Defender

The DLL file might also be infected with malware or virus and to eliminate it which could explain why you’re getting the “DLL is either not designed to run on Windows or it contains an error”. Thus, you have to scan your computer using security programs like Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.

As you know, Microsoft’s consumer cloud storage platform is none other than OneDrive. It is where users can save any of their files albeit it’s mostly used to store common files like documents and photos. However, there are times when you might encounter some problems when saving these files. Recently, some users reported that they had problems saving Word documents to OneDrive and if you experience the same issue, then you’ve come to the right place as this post will guide you on how to resolve it. According to users who encountered the problem, when they try to save Word documents on OneDrive, an error message appears instead stating, “This is not a valid file name”. This kind of error only occurs when the file is opened from within OneDrive for saving in a different folder. In other words, if the file is saved in the same folder, the error won’t pop up but if it is saved in a separate folder, that’s when the error appears. Worry not though for fixing this error is not complicated and won’t take too long. It seems that this error is due to the 259-character limitation when creating and saving files as far as the Office products are concerned. To resolve it, there are several workarounds you can check out. Before you proceed with these workarounds, make sure that you have a stable internet connection.

Option 1 – Try renaming the file with a shorter name

The first thing you can do to fix the problem is to rename the file with a shorter name. Just right-click on the file and select the Rename option from the menu and then type in the new name and click OK or tap Enter to rename the file.

Option 2 – Try renaming the folders where the file is located

Like what you did in the first given option, all it takes is a right-click but this time on a folder. Rename the folder with a different name and save the changes made and then check if you can now save the Word document on OneDrive.

Option 3 – Try moving the file to a folder with a shorter path

If the first two options didn’t work, you can try moving the file to a folder with a shorter path. Note that it is not the same as doing it locally on a Windows 10 computer so you have to right-click on the file and select the “Move to” option. After that, locate the folder where you want to move the file and select it and then click on the Move button to complete the task.

Option 4 – Try making some changes in the document

You could also try to make some modifications to the document. Once you’ve done that, click the File tab and select the Save As option and then go to the folder where you want to save the file and tap enter.

From their infant stages to modern days, computer viruses were always kind of here. From simple ones that were annoying with playing speaker sounds and throwing messages on screen to more malicious ones capable of deleting and encrypting files. In today's modern world it is very important to protect yourself, modern viruses are not a joke anymore and they are aimed to create serious damage to computer systems. They can encrypt files in order to make you pay for a decrypter, they can straight up delete files or even cause some hardware damage. Like mentioned before protecting yourself is important, but protecting does not mean only having antivirus software installed, information, where are common places in which they lurk and could be picked up, is also very important. That is why we are exploring in this article the most common place where you can pick viruses or other malware.

Downloading Programs

Programs that contain the downloadable files are the commonest source of malware such as freeware, worms, and other executable files. Whether you download an image editing software, a music file, or an e-book, it is important to ensure the reliability of the source of the media. Unknown, new, or less popular sources should be avoided.

Pirated or Cracked Software

Are you aware of software cracking? Well, every time you open cracked software, your antivirus software might flag it as malware as the cracks consist of malicious scripts. Always say “No” to cracks as they can inject malicious script into your PC.

Email Attachments

Anyone can send you an email attachment whether you know them or not. Clicking on unknown links or attachments can harm your device. Think twice before clicking anything and make sure that file type is not ‘.exe’.

Internet

One of the easiest ways to get a virus on your device is through the Internet. Make sure to check the URL before accessing any website. For a secured URL always look for ‘HTTPS in it. For example, when you click videos published on social media websites, they may require you to install a particular type of plug-in to watch that video. But in reality, these plug-ins might be malicious software that can steal your sensitive information.

Booting Data from Unknown CDs

Malicious software can get into your device through an unknown CD. A good practice to be safe from malicious infection is to remove CD when your device is not working at all. Your system could reboot the CD if it is not removed before switching off the computer.

Bluetooth

Bluetooth transfers can also infect your system, so it is crucial to know what type of media file is being sent to your computer whenever a transfer takes place. An effective armor would be to allow Bluetooth connectivity with only known devices and activate it only when required.

Unpatched Software

Often overlooked, unpatched software is also a leading source of virus infection. Security holes in software are exploited by attackers and are unknown to software makers until the attackers release them in the form of zero-day attacks. It is therefore recommended to install software updates as soon as they are available on your PC.
