• 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 mscorlib.dll
• If registering 32-bit DLL on a 64-bit Windows, then enter the following command instead: regsvr32 c:\windows\syswow64\mscorlib.dll

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.
