Visual Studio 2015: The hash value is not correct

Question

After installing Visual Studio Professional 2015 (using an RTM executable but selecting Update 2 during the setup process), I get the following warning:

Eve

Answer 1

In my case, it was because my internet was restricted. I had to download off-line copies of Visual Studio for SQL and SSDT. The instructions below, however, are for Visual Studio 2017.

1. Download: https://go.microsoft.com/fwlink/?LinkId=866452
2. SSDT-Setup-ENU.exe /layout
3. Download: https://aka.ms/vs/15/release/vs_sql.exe
4. vs_SQL.exe --layout (this takes a while, it's laying out ~4 GB)
5. \vs_setup.exe --wait --nickname "SSDT" --passive
6. \SSDT-Setup-ENU.exe

Notes: For #2, yes it's "15" even though you're downloading Visual Studio 17. I think it ha to do with Visual Studio 2017 being at version 15 and Visual Studio 2015 being at version 17.
