To re-register all DLL files, you can follow these steps. To re-register a specific DLL file, run the command as administrator. Then, type the following command.
Create an Exception Windows Defender
Sometimes, the Windows Defender can stop an application from accessing some files. If the Defender detects a threat from any DLL file, it will attempt to safeguard the computer by not letting the application use the DLL file, and hence the missing error is displayed. You can give the application full access by creating an exception in the Windows Defender. Here’s how you can do it. If you are on Windows 10, search for Windows Security on the search box. Then click on Virus and threat protection and continue from step 3.

All Types of UnityPlayer.dll Errors
Few UnityPlayer.dll errors that we see most frequently are explained below. However, you can get these errors from any DLL file.
UnityPlayer.dll caused an Access Violation (0xc0000005)
If a DLL file tries to access the restricted files, the computer displays the error “.dll caused an Access Violation,” crashing the application/game. Sometimes, the error will read (0xc0000005) at the end of the error. 0x represents the address of the RAM. Lower addresses, such as 0xc0000005, are reserved for the BIOS or the Operating System. Therefore, if some DLL file tries to access these reserved memory addresses, we’ll get the access violation error. Now, let’s check what causes this error and fix it. You can try the following fixes to fix a DLL access violation error.
Disable the XMP (Extreme Memory Profiles)
Extreme Memory Profiles, or XMP, is an Intel technology that allows you to boost memory speed without overclocking your RAM. XMP profiles effectively will enable you to configure high-performance RAM that exceeds its specifications. Sometimes, enabling the RAM XMP profile also causes the access violation error. The RAM will run at a slower speed if XMP is turned off, which may prevent the app from crashing. To disable the XMP, you need to enter the BIOS setting in your motherboard. Depending on the motherboard, a section will read X.M.P. that is either enabled or disabled (on or off). Make sure the setting is disabled or off.
Reset the BIOS (Basic Input Output System)
If you have done any overclocking to your RAM, you might want to revert it to fix the issue. Resetting the BIOS to factory default will remove any overclocking. Note: Resetting the BIOS will not reset the OS Here are a few methods you can try to reset the BIOS.
You can use the BIOS settings to reset the BIOS itself. Reseating the CMOS will reset all the BIOS settings. If you cannot reseat the CMOS, you can reset the CMOS jumper.
Uninstall Citrix
Sometimes, if you have Citrix Receiver or Citrix Workspace installed on your computer, it can cause some access violation issues when running some games. Try uninstalling Citrix by following these steps to see if it fixes the problem.
UnityPlayer.dll Not Found/Missing
We get this error if the application cannot find the desired DLL file to complete its process. The solutions that are mentioned above will fix the DLL missing issue.
UnityPlayer.dll Caused a Privileged Instruction (0xc0000096)
The privileged instruction is also a type of access violation error. A Privileged Instruction is a processor operating code (assembler instruction) that can only run in Ring-0 mode. Ring-0 has the most privileges and interacts with physical hardware such as the CPU, memory, and protected data directly. Regular applications run in Ring-3 mode, which prevents them from directly accessing the CPU, memory, or protected data. Therefore, if a DLL file tries to access physical hardware like CPU and memory, we get the privileged instruction error.
UnityPlayer.dll crash
Unstable internet while downloading can cause a DLL file to be corrupted. Therefore, when a program tries to run a corrupted or incomplete DLL file, the application will crash, displaying the DLL crash error.
