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

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

Note: The steps are slightly different for Windows 32 Bit and 64 Bit. Most modern Windows systems run on 64 Bit architecture. If you are unsure, follow the steps for 64 Bit.

  1. Download the cdosys.dll from this page to your Windows computer. The file will download as a zip file. Extract it to get the dll file.
  2. Copy the cdosys.dll file to the Windows System folder. The location of the system directory depends on the DLL file architecture and your OS architecture:
    • 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 cdosys.dll
    • If registering 32-bit DLL on a 64-bit Windows, then enter the following command instead: regsvr32 c:\windows\syswow64\cdosys.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 cdosys.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 cdosys.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 cdosys.dll file is part of. Make sure it is not even running in the background.
  3. Copy the cdosys.dll file and go to the folder where the game or application is installed on your Windows.
  4. Paste the cdosys.dll.
  5. Reboot your Windows machine.

Try to open the game or application that requires the cdosys.dll file and see if the issue is fixed.

Method 3: Reinstall or update the game or software that requires cdosys.dll

  • Make sure you have the latest version of the game or software. If there is an update, download and install the same.
  • Reinstall the game or software and check if the cdosys.dll errors are resolved.

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.
