How To Fix unityplayer.dll not found error in Windows 10

The file known as a “Dynamic Link Library” (DLL) includes hundreds of lines of code that are accessible to several apps at the same time. Errors are referred to as missing DLL files, and they occur whenever a programme is unable to locate a necessary DLL file in order to function properly.

As a result, you will see a dialogue box that states “.dll file missing,” which will cause the game or programme to become unresponsive.

What is a DLL File?

Although the.exe (Executable) file is where we begin when attempting to execute any application, it does not always include all that is necessary to successfully run the programme. The majority of programmes get their code for performing their tasks from other libraries. These programme instructions are bundled together and stored inside the DLL files so that any application may make use of them.

The DLL files contain code that may be utilised concurrently by several different programmes.

What is UnityPlayer.dll?

UnityPlayer.dll is a file that is part of a Dynamic Link Library that enables the creation of 3D content for use in video games and animated characters. This file may be used in the creation of games, as well as the addition of effects to such games.

What Causes UnityPlayer.dll Missing Error?

The DLL file missing error occurs if a DLL file is corrupted, removed, or prevented from being accessed by antivirus software. The following are a few of the reasons why the DLL files are unable to access the files:

  • Windows Defender places restrictions on access.
  • Eliminated by the Antivirus Program
  • A virus infects the DLL file.
  • DLL files that are corrupted
  • An error in Unity

How to Fix UnityPlayer.dll Not Found Error?

You can try the following fixes for any DLL file missing error.

Restore DLL Files

During the process of installing or downloading a programme, the DLL files might get damaged on occasion. It’s possible that these corrupted files are to blame for the programme reporting that a DLL file is missing from its cache.

You may restore any DLL files by following these instructions in the appropriate order.

  • The appropriate DLL files may be found on the internet and need to be downloaded and extracted. You may get any DLL file you need by going to the website dll-files and downloading it from there.
  • Find the DLL files that are causing the problem and remove them. If the file in question is a UnityPlayer.dll, you may find it within the location specified by the programme folder.
  • It is necessary to remove the DLL file that is causing the issue and then to replace it with the DLL file that was removed.

Start the programme and observe whether or not the crash notice appears. In the event that it does, you will need to re-register the DLL file.

Re-register the DLL

You have the option of re-registering these files in case the DLL files have been damaged. When you do this, any corrupted part will be removed and a new file will be added in its place.

You may follow these instructions to re-register all of the DLL files on your computer.

  • While holding down the Windows key and the R key, enter “cmd.”
  • To execute the command with administrative privileges, use Ctrl+Shift+Enter.
  • Enter this command into the prompt. After that, hit the enter key.

  • At this point, you must wait for each and every file to re-register. When the procedure has been finished, you will be able to restart the computer.

Execute the command with administrative privileges in order to re-register a particular DLL file. After that, enter the following command into the console.

regsvr32 <path and filename of dll>

Create an Exception Windows Defender

The Windows Defender may sometimes prevent a programme from accessing certain files if it detects a threat. In the event that the Defender identifies a potential security risk posed by a DLL file, it will make an effort to protect the computer by preventing the programme from using the DLL file. As a result, the missing file error will be shown.

By making an exception in Windows Defender, you will be able to provide the programme with unrestricted access. Detailed instructions are provided below.

  • From the Start menu, choose the Settings option.
  • Navigate to “Virus and threat prevention” under “Windows Security” in the Privacy and Security menu.
  • There will be a new dialogue box that appears. Choose Manage settings from the menu that appears under Virus and threat protection settings.
  • Click the Add or delete exclusion button after scrolling down to the Exclusion section.
  • After clicking on Add an exclusion, go to the File menu.
  • Find the file that contains your application’s executable and then hit the Open button.

If you are using Windows 10, look in the box that says “search” for “Windows Security.” After that, choose the Virus and threat protection option, and proceed with step 3 from there.

Run System File Checker

Your operating system’s faulty system files will be repaired by the System File Checker utility if it is installed. In the event that the system is unable to locate the DLL files because of damaged files, running the system file checker may be able to resolve the issue.

You may follow these instructions to run the System File Checker on your computer.

  • While holding down the Windows key and the R key, enter “cmd.”
  • To execute the command in an administrative capacity, use Ctrl + Shift + Enter.
  • Now, hit Enter after typing “SFC /scannow” in the input box.

The System File Checker will start now. After the process is complete, restart your computer.

Run DISM

The DISM tool, which stands for “Deployment Image Servicing and Management,” is used to examine, scan, and correct any issues that may exist with the health of the computer. If you get an error message stating that a System32 DLL file is missing, using the DISM command might assist you in repairing or replacing the missing files.

CheckHealth, ScanHealth, and RestoreHealth are the three different commands that come with DISM.

To execute the instructions that are provided below, you will need to launch the Command Prompt as an administrator.

  • CheckHealth: This command checks to see if any local Windows files are corrupted.
    DISM /Online /Cleanup-Image /CheckHealth
  • ScanHealth: The ScanHealth command runs a thorough check to discover if the OS has any issues.
    DISM /Online /Cleanup-Image /ScanHealth
  • RestoreHealth: You can use DISM and the RestoreHealth option to scan and repair errors automatically.
    DISM /Online /Cleanup-Image /RestoreHealth

How to Install UnityPlayer.dll?

During the course of the installation procedure, all of the necessary files that are needed by the programme will be installed automatically. You may, however, get the DLL files from dll-files in order to either add the ones that are missing or change the ones that are already there if you wish to replace the UnityPlayer.dll file.

Copy the contents of the downloaded file, then extract it, and place it in the same folder as the executable file. You are required to register a DLL file whenever System32 is updated with a new version. In the Command Prompt window, type the following command: (run as admin).

for %i in (%windir%\system32\*.dll) do regsvr32.exe /s %i

The above code will register all the DLL files inside System32.

All Types of UnityPlayer.dll Errors

The following are some of the most common UnityPlayer.dll issues, along with their explanations. On the other hand, these issues are possible in every DLL file you use.

UnityPlayer.dll caused an Access Violation (0xc0000005)

If a DLL file attempts to access restricted files, the computer will show the error message “.dll caused an Access Violation,” and the programme or game will become unusable as a result. At the very end of the error, it will sometimes read “0xc0000005” in certain instances. The address of the RAM is denoted by the value 0x. The Basic Input/Output System (BIOS) or the Operating System can only access lower addresses, such as 0xc0000005.

Because of this, we will get the access violation error whenever any DLL file attempts to access the memory locations that have been reserved for them. Now that we know what the problem is, let’s go ahead and solve it.

You may attempt to repair a DLL access violation problem by using the following workarounds.

Disable the XMP (Extreme Memory Profiles)

Extreme Memory Profiles, sometimes known as XMP, is a technology developed by Intel that enables users to increase memory performance without having to overclock their RAM. You will be able to successfully set high-performance RAM that surpasses its specs via the use of XMP profiles.

There are certain instances in which activating the RAM XMP profile also results in the access violation error. If XMP is disabled, the pace at which the RAM operates will be slowed down, which may prevent the application from crashing.

Entering the BIOS setting on your motherboard is required in order to turn off the XMP feature. There may be a portion on the motherboard that reads X.M.P. and it may be activated or disabled (on or off). Check to see that the setting has been turned off or disabled.

Reset the BIOS (Basic Input Output System)

If you have overclocked your RAM in any way, you will need to reset it to its factory settings in order to resolve the problem. Any overclocking will be removed from the system when the BIOS is restored to its factory settings.

  • You are able to reset the BIOS itself by using the options in the BIOS.
  • Simply resetting the CMOS will clear all of the settings in the BIOS.
  • It is possible to reset the CMOS jumper if you are unable to reseat the CMOS.

Uninstall Citrix

When you run certain games on a computer that also has Citrix Receiver or Citrix Workspace installed, you may see access violation errors. These errors may be avoided by uninstalling these programmes. If the issue still persists, you may give the uninstalling of Citrix a go by following these instructions.

  • To access the Control Panel, choose it from the Start Menu.
  • In the upper-right corner of the Control Panel dialogue box, choose the View by option, and then select Large icons from the drop-down menu.
  • Select Programs and Features from the menu.
  • Click the Uninstall button after selecting Critix.
