1. Temporarily disable the antivirus protection
Your antivirus program can delete or quarantine certain files, patches or Dlls associated with programs, games or even apps. The reason why this is happening is because the antivirus scanning engines might misinterpret files that can be trust with potential harmful packages.
So, in this case you should try to verify the quarantine list as there you might find the file that’s missing from this certain program, app or game. You can then restore it, or if that isn’t working you should follow instead:
- Disable the antivirus protection for a few minutes.
- Uninstall the program which is not running and which is showing the Dll error 126/127 problem.
- Then, reinstall this program from the beginning.
- With the antivirus disabled, run the program as now it should run properly.
- If it does, add an exclusion rule within your security software for better protecting the files associated with this app.
2. Uninstall or reinstall the program
Sometimes, while a certain program is installed on your computer something is happening and the installation process gets corrupted. In most situations, you are not prompted with errors, so you might think that your program was properly configured. But, in fact there might be corrupted files that can cause the DLL errors 126 and 127 event. Well, there is an easy fix for this issue as all you need to do is to repair the program involved.
You can do that by running the uninstall sequence – if the ‘repair’ option is available, choose it. Otherwise complete the removal process and then reinstall the app from the beginning.
You can remove a program from your Windows 10 system easily by using the file’s own uninstaller or by going to Control Panel:
- Click on the Windows search icon (next to the Windows Start button) and type Control Panel – then, click on the first result that’s displayed.
- In Control Panel, switch to Category tab.
- Then, choose ‘Uninstall a program’ under Programs.
- Find the program that you want to remove, select it and then pick ‘uninstall’.
- That should be all.
3. Update Microsoft NET Framework
If Microsoft NET Framework is outdated, you might experience these two DLL errors. So, you should also try to update this built-in software as it might help you fix the problem.
In order to do so, access Microsoft’s dedicated webpage from here and download the latest version of Net Framework.
4. Run the DirectX End-User Runtime Web Installer toolkit
Reinstalling DirectX can also address DLL problems. This is also a program developed and offered by Microsoft. To reinstall it on your computer, go to Microsoft’s official webpage (or access this link). Use the search engine, enter DirectX and just download the DirectX End-User Runtime Web Installer.
Save it on desktop, run the executable file and follow on-screen prompts for resuming the flashing process. Reboot your Windows 10 system at the end.
5. Initiate a system check
If system corrupted files are causing the DLL error 126/127 event, then you should run a Windows troubleshooter engine to automatically fix the problem. Here is what you need to follow:
- On your computer open an elevated command prompt window: right click on the Windows Start icon and from the list that’s displayed choose ‘Command Prompt (Admin)’.

- A scan will be automatically initiated and completed.
- If errors are found, the Windows system will try to fix them.
