Here are the detailed steps to fix the sechost.dll errors.

Method 1: Manually install sechost.dll on Windows System Folder and Register the dll.

    • For 64-bit Windows, the 64-bit DLL files should be copied to the C:\Windows\System32\ directory and the 32-bit DLL files should be copied to the C:\Windows\SysWOW64\ folder.
    • For 32-bit Windows, the file should be copied to the C:\Windows\System32\ folder.
  3. Next, search for Command Prompt on your computer > Right Click > select Run as administrator.
  4. Execute this command: regsvr32 sechost.dll
    • If registering 32-bit DLL on a 64-bit Windows, then enter the following command instead: regsvr32 c:\windows\syswow64\sechost.dll
  5. Restart your computer.

Try to relaunch the software or game and see if the issue is fixed. If not, proceed to read the next section.

Method 2: Manually install the sechost.dll file on application or game folder

Sometimes, you may need to place the dll file in the folder of the game or application that it is a part of. 

  1. Download the sechost.dll file from this page to your Windows system and have it ready. The file will download as a zip file. Extract it to get the dll file.
  2. Quit the software or game that the sechost.dll file is part of. Make sure it is not even running in the background.
  3. Copy the sechost.dll file and go to the folder where the game or application is installed on your Windows.

Method 4: Scan your Windows system for virus and malware

  • Completely scan your Windows machine to see if you have any vulnerabilities such as virus or malware. It is not a good idea to rely on Windows Defender - even though it has gotten quite good over the years, it is definitely not as good as a dedicated Antivirus program.
  • If there is indeed any virus or malware issue, try to clean it up using the Antivirus program. 
  • Try to restore your Windows to an earlier point of time if you have a system restore point.
  • When all else fails, do a fresh reinstall of your Windows operating system.
