Loadlibrary Failed with Error 126? Here’s How to Fix it

The ‘loadlibrary failed with error 126’ is an error that dates back to the earlier Windows versions (Vista and onwards) but is still reported. The issue is reported when launching an application/game or installing it.

Loadlibrary Failed with Error 126 Fix

Many programs showed this error. Following are a few examples of such applications, games, utilities:

  • Rhinoceros 3D
  • Adobe Suite (Photoshop, Illustrator, etc.)
  • TrackIRv5
  • UltimateDefrag
  • Radar ScreenSaver
  • Logitech Gaming Keyboard and Headset
  • Minecraft
  • BluetStacks
  • Steam or Steam Games (like Stardew)
  • Virtual Box
  • PowerAttendantLite
  • Blender
  • Civilization VI
  • ANSYS
  • Microsoft Remote Desktop
  • MATLAB

Many factors can cause the ‘loadlibrary failed with error 126’ but the following can be regarded as the main culprits:

  • Missing Admin Privileges: If the application (like NetBeans) cannot access protected system files or directories due to the absence of admin privileges, it may result in a loadlibrary error.
  • Corrupt or Outdated Graphics Driver: If the system’s graphics driver is corrupt or outdated, then its incompatibility with the problematic application may lead to the error 126.
  • Dual Graphics Cards: If the system has two graphics cards i.e., a switchable graphics system with one built-in graphics card and the other dedicated, then it can cause the loadlibrary issue if the application modules try to use both cards at the same time.
  • Corrupt System Files: If the essential system files are corrupt, then an application may fail to access an essential directory or file, resulting in the loadlibrary failed with error 126.

Launch the Problematic Application as an Administrator

You may encounter the loadlibrary failed with error 126 when the problematic application does not have the privileges to access a protected system resource. In this case, launching the problematic application as an administrator may solve the problem.

  1. Right-click on the shortcut icon of the problematic application (or in the search results of the start menu) like Adobe Illustrator.
    Run Illustrator as Administrator
  2. Now select Run as Administrator and check if the application launches fines.
  3. If so, close the application and again launch it normally (not as administrator) and check if it is working fine.
  4. If not, then right-click on the shortcut of the problematic application (like Adobe Photoshop) and select Properties. In case, the start menu search is used, select Open File Location, right-click on Illustrator, and select Properties.

Enable Virtual Super Resolution in the AMD Settings

VSR (or Virtual Super Resolution) is an AMD feature that lets an application or game render at higher resolutions (beyond the native display resolution). If the display resolution in use is not compatible with the game (like Civilization VI), then that may cause the loadlibrary error at hand. In this context, enabling the Virtual Super Resolution in the AMD Settings may solve the problem.

  1. Open the AMD Software and click on Settings (near the top right corner).
  2. Now head to the Display tab and under Display Options, enable Virtual Super Resolution.
    Enable Virtual Super Resolution in AMD Settings
  3. Then launch the problematic game (like Civilization VI) or application and check if the loadlibrary issue is resolved.

Copy the DLL File to the System32 Directory

You may encounter the issue under discussion if an essential DLL file is missing from the System32 directory and copying the same may solve the problem.

  1. Right-click Windows and open Run.
    Open the Run Command Box from the Quick Access Menu
  2. Now navigate to the following:
    C:\Windows\System32\DriverStore\FileRepository\u0352938.inf_amd64_e098709f94aef08d\B352876
  3. Then copy the atio6axx.dll file and paste it into the following directory:
    C:\windows\system32
  4. Now restart the system and upon restart, launch the problematic application (like ArcMap) to check if it is working fine.
  5. If not, click Windows, search, right-click Command Prompt, and select Run as Administrator.
    Open Command Prompt as Administrator
  6. Then execute the following (copy/paste the command, otherwise, make sure the spacing is right):
    C:\Windows\System32\ copy atio6axx.dll .dll
    Copy atio6axx.dll File
  7. Now restart the system and upon restart, check if the loadlibrary error is cleared.

Change the Main Monitor or Disconnect the External Display

In a multi-display environment, you may encounter the loadlibrary failed error if the main monitor is not the internal display (in case of a laptop) or if the external display is not connected to a dedicated graphics card port but to an on-board graphics card port (in a dual graphics cards setup) as this may cause incompatible resource hogging by the cards. In such a case, changing the main monitor of the system or disconnecting the external display may fix error 126.

  1. Right-click Windows and open Settings.
    Open Windows Settings
  2. Now, in the System tab, open Display and expand Multiple Displays.
    Open Display in the System Tab of the Windows Settings
  3. Then select the Internal Display (you may use the Identify button to find out which display belongs to what) and checkmark Make This My Main Display.
    Set the Laptop’s Internal Display as the Main Display
  4. Now launch the application in question (like Adobe Photoshop) and check if it is operating fine.
  5. If not, check if connecting the external display to another port (or swapping monitors’ ports) solves the problem.
  6. If that did not work, disconnect the external monitor from the system and restart the system.
  7. Upon restart, launch the problematic application and check if it is working fine. If so, then you may connect back the external monitor.

Perform an SFC Scan of the System

The loadlibrary may fail with error 126 if the essential system files are corrupt which may not let an application access an essential system directory or resource. In this case, you may fix the issue by performing an SFC scan of the system.

  1. Perform an SFC scan of the system and wait till the scan is complete. Make sure to launch the Command Prompt as an administrator. Moreover, this scan may take some time to complete, so try it in your spare time (or overnight).
    Perform an SFC Scan
  2. Once the SFC scan is completed, check if the loadlibrary problem is solved.

Perform a Clean Boot of the System

The loadlibrary error might occur if a process/service on the system is interfering with the problematic application’s execution. In such a case, ending the conflicting processes in the Task Manager or performing a clean boot of the system may clear the error 126.

End Conflicting Tasks in the Task Manager

  1. Right-click Windows and open Task Manager.
    Open the Task Manager of the System Through the Quick Access Menu
  2. Now end all the processes related to Intel and then check if the issue is resolved.
    End Intel Related Processes in the Task Manager
  3. If not, then check if ending all the non-essential processes or processes related to the problematic application (like Adobe processes if the issue is occurring with an Adobe application like Photoshop) solves the problem.

Perform a Clean Boot of the System

  1. Perform a clean boot of the system (make sure to disable Radeon Software in the Startup tab of the Task Manager) and check if the loadlibrary issue is cleared. If so, then you may enable back the processes one by one till the problematic one is found. Once found, either keep it disabled or uninstall it.
  2. If the issue persists, check if booting the system into the Safe Mode solves the problem.

Uninstall AMD Software

There are many applications (found by clean booting the system) reported to cause the loadlibrary issue but in many instances, users reported that the AMD Software triggered the error. Here, uninstalling the AMD Software may solve the problem.

  1. Right-click Windows and open Apps & Features.
    Open Apps & Features
  2. Now, in front of AMD Software, click on three vertical ellipses and select Uninstall.
    Uninstall AMD Software
  3. Then confirm to uninstall AMD Software and follow the prompts on the screen to uninstall it.
  4. Once uninstalled, restart the system, and upon restart, check if the loadlibrary problem is solved.

Disable the System’s Built-in Graphics Card

You may encounter loadlibrary error 126 if the system has two graphics cards (i.e., one built-in and the other dedicated) and the modules of the applications involved tried to use different cards simultaneously.

For example, if the issue occurs when an RDP session is used to launch Blender and the loadlibrary error is shown, then the issue might have occurred as the RDP session tried to use a built-in graphics card, whereas, Blender was trying to use the dedicated graphics card. In this scenario, disabling the built-in graphics card (after all, dedicated graphics is more powerful and useful) will force the usage of a single card and thus may fix the LoadLibrary error.

  1. Right-click Windows and open Device Manager.
    Open Device Manager Through the Quick Access Menu
  2. Now expand Display Adapters and right-click on the built-in graphics device (like an Intel one).
    Disable Intel Graphics Card in the Device Manager
  3. Then select Disable Device and afterward, confirm to disable the graphics device.
  4. Now launch the problematic application or pair of applications (like RDP and Blender) and check if the loadlibrary failed error is cleared. Keep in mind, you can enable the built-in graphics device afterward.
  5. If that did not work, check if disabling and enabling the dedicated graphics card (like an AMD card) solves the problem.

Edit the System’s Group Policy for Remote Connections

If the issue is occurring when a remote connection is used to access the system, then the improper usage of graphics properties of the host may trigger the issue at hand. Here, editing the system’s Group Policy about the remote connection to force the proper usage of the graphics properties may solve the problem.

  1. Click Windows, search, and open Edit Group Policy.
    Open Edit Group Policy
  2. Now navigate to the following path:
    Computer Configuration>> Administrative Templates>> Windows Components>> Remote Desktop Services>> Remote Desktop Session Host>> Remote Session Environment
  3. Then disable the option of Use WDDM Graphics Display Driver for Remote Desktop Connections and close the editor.
    Disable Use WDDM Graphics Display Driver for Remote Desktop Connections in the Group Policy Editor
  4. Now restart the system and upon restart, check if the loadlibrary error 126 is cleared.
  5. If not, open the Group Policy Editor and make sure the following are set as Enabled:
    Use Hardware Graphics Adapters for All Remote Desktop Services
    
    Prioritize H.265/AVC444 Graphics Mode for Remote Desktop Connections
    
    Configure H.264/AVC Hardware Encoding for Remote Desktop Connections
    Enable Relevant Graphics Settings in the Group Policy Editor
  6. Then close the Group Policy Editor and restart your system.
  7. Upon restart, check if the loadlibrary issue is resolved.

Uninstall A Java Version

If an application (like Minecraft) requires JAVA but the system has two Java versions installed (like a 32-bit and other, 64-bit), then that may break the operation of the application and cause loadlibrary failed with error 126. In this case, uninstalling a Java version may solve the problem.

  1. Right-click Windows and open Apps & Features.
  2. Now check if there is more than one Java version installed.
  3. If so, uninstall the 64-bit version and afterward, restart the system.
    Uninstall Java 64-bit Version
  4. Upon restart, check if the system is cleared of the libraryload error.
