Copy the UnityPlayer.dll file from another computer

Let’s see all these fixes in detail.

1] Uninstall and reinstall the game or program

One of the causes of the missing DLL files error is improper installation. If you have terminated the installation process of your game or program or if the power was shut down unexpectedly during the installation of the game or program, some of the files might have been corrupted. In this case, reinstalling the game or program fixes the issue. Windows is also suggesting you reinstall the problematic program (read the error message).

Uninstall the game or program via the Windows 11/10 Settings app, then download the game again. Now, run the installer file to install the game again. Make sure that the installation process is not terminated this time.

2] Move all the files to the game installation folder

By default, all the programs and games are installed on our C drive. Installing a larger game on the driver will obviously take up more space on the drive. This can create performance issues. To free up space on the C drive, some users move the game files from the installation folder to another location (on another hard drive partition). Doing this causes issues in that game. If you have done such a thing, the game is showing the “UnityPlayer.dll is missing or not found” error due to this. To fix this problem, move all the files to the game installation folder.

If you did not move the game files from the game installation folder to another location and the game is showing you the error message, check if the game exe file is located inside the game installation folder. If not, the exe file is placed at another location. Now, click on Windows Search and type the name of your game. Right-click on it and select Open file location. You will find the exe file there. Now, copy that exe file and paste it into the game installation folder. After that, right-click on the exe file placed inside the game installation folder and create a desktop shortcut for the same. Now, launch the game from this desktop shortcut.

3] Copy the UnityPlayer.dll file from another computer

If the problem still persists, copy the UnityPlayer.dll file from another healthy computer to your computer. You will find the UnityPlayer.dll file only on that computer that has the program or game which requires the UnityPlayer.dll file is installed. For this, you can contact your friends who play the same game you are experiencing the issue with.

By default, the DLL files are located at the following location on a Windows PC:

C:\Windows\System32

Apart from the above location, the DLL files are also located in the game installation folder. Therefore, you have to look for the UnityPlayer.dll file at both locations.

This should fix the issue.
