  2. Copy the "Nv4.dll" library and paste it into the "C:\Windows\System32" directory.
    Copying the Nv4.dll library into the Windows/System32 directory
    Step 2:Copying the Nv4.dll library into the Windows/System32 directory
  3. If you are using a 64 Bit operating system, copy the "Nv4.dll" library and paste it into the "C:\Windows\sysWOW64" as well.
    NOTE! On Windows operating systems with 64 Bit architecture, the dynamic link library must be in both the "sysWOW64" directory as well as the "System32" directory. In other words, you must copy the "Nv4.dll" library into both directories.
    Pasting the Nv4.dll library into the Windows/sysWOW64 directory
    Step 3:Pasting the Nv4.dll library into the Windows/sysWOW64 directory
  4. In order to complete this step, you must run the Command Prompt as administrator. In order to do this, all you have to do is follow the steps below.
    NOTE! We ran the Command Prompt using Windows 10. If you are using Windows 8.1, Windows 8, Windows 7, Windows Vista or Windows XP, you can use the same method to run the Command Prompt as administrator.
    1. Open the Start Menu and before clicking anywhere, type "cmd" on your keyboard. This process will enable you to run a search through the Start Menu. We also typed in "cmd" to bring up the Command Prompt.

  5. Paste the command below into the Command Line window that opens and hit the Enter key on your keyboard. This command will delete the Nv4.dll library's damaged registry (It will not delete the file you pasted into the System32 directory, but will delete the registry in Regedit. The file you pasted in the System32 directory will not be damaged in any way).
    %windir%\System32\regsvr32.exe /u Nv4.dll
    Uninstalling the Nv4.dll library from the system registry
    Step 5:Uninstalling the Nv4.dll library from the system registry
  6. If the Windows you use has 64 Bit architecture, after running the command above, you must run the command below. This command will clean the broken registry of the Nv4.dll library from the 64 Bit architecture (The Cleaning process is only with registries in the Windows Registry Editor. In other words, the dynamic link library that we pasted into the SysWoW64 directory will stay as it is).
    %windir%\SysWoW64\regsvr32.exe /u Nv4.dll
    Uninstalling the broken registry of the Nv4.dll library from the Windows Registry Editor (for 64 Bit)
    Step 6:Uninstalling the broken registry of the Nv4.dll library from the Windows Registry Editor (for 64 Bit)

    Step 8:Creating a clean and good registry for the Nv4.dll library (64 Bit için)
