Help on downloading the SQL Tools Service layer for SQL Server (mssql) Extension

[azhuang735]

I've been having trouble downloading the mssql SQL Server extension on VSCode and the output is saying that it's installing SQL tools service to my .vscode\extensions\ms-mssql.mssql-1.34.1\sqltoolsservice\5.0.20250715.3\Windows directory, but it fails and it fails with a error code 407.

I was provided the link to the github page for the service layer that I'm missing:
https://github.com/Microsoft/sqltoolsservice/releases/download/5.0.20250715.3/microsoft.sqltools.servicelayer-win-x64-net8.0.zip

But I'm not sure how I'm supposed to append this to the extension. I've tried downloading and extracting the contents of the zip file into the directory described earlier, but that didn't work. Can someone please guide me on this installation to get the extension to work?
