I don't know what the actual problem is. So, I can not explain how this work. But this trick worked for me. I assume you have downloaded the installer. Now copy vs_SKU.exe (Ex: vs_professional.exe) and vs_installer.opc from the downloaded directory to a new directory/folder for safety. Open command prompt from the new directory. You can do this by holding shift+right click on blank space and select Open command window here. Copy the following command and press enter.

vs_professional.exe --layout e:\vs2017offline --lang en-US --add vs_installer.opc

Note: Red marked text means where to download the vs_installer.opc file.

If you can not find the vs_installer.opc file after finishing the download then use this search tool to search the file (Download Everything). When you find the new file replace it with the original file.

Make sure to install certificates from certificate directory.

Now run vs_professional.exe

Hope this will help you.
