Installing SQL Server Data Tools (SSDT for SSAS, SSIS or SSRS) on Visual Studio 2017 or earlier

Do you have Visual Studio 2015 or 2017 and want to use SSAS, SSIS or SSRS? If so, you need to:
1. Have already installed SQL Server Developer, Standard or Enterprise, and
2. Have installed Visual Studio.
If you have done this, then you also need to install SQL Server Data Tools (SSDT). This is still available, and in this video I'll show you:
1. Where you can download it from, and
2. How to install it (it's fairly easy!).

I keep getting Error I don't know why

I got the 'Successful' message at the end. But it didn't ask me to restart the computer. When check under the new project SSIS was the only one under business intelligence but the other two (SSRS and SSAS) are right outside and above the business intelligence drop down. Is it alright?
