Microsoft SQL Server Reporting Services 2017 registry - reporting-services

Question

Did registry paths change for the Microsoft SQL Server Reporting Services 2017?
Before we were able to locate instance name here:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\RS\MSSQLSERVER
But now in 2017 MSSQLSERVER is missing and it has SSRS instead.
Based on this article it should be still under MSSQLSERVER but it's not. Did we missed some installation setting that caused this or this is default standard behavior now?

Answer 1

Because Reporting Services is now a separate installation, it installs as a named instance SSRS. This is a change from previous versions where Reporting Services was part of SQL Server setup.
I would suggest using WMI queries to obtain the necessary information (example below using PowerShell). Notice that the v14 refers to the 2017 release.
$wmiName = (Get-WmiObject –namespace root\Microsoft\SqlServer\ReportServer –class __Namespace).Name
$rsConfig = Get-WmiObject –namespace "root\Microsoft\SqlServer\ReportServer\$wmiName\v14\Admin" -class MSReportServer_ConfigurationSetting

Answer 2

I know this post is old but I had the same problem in my company to find information from RS 2017 and found no place that reported the right location so I wanted to post here!
My friend (Paulo Henrique Rodrigues Orind) and I found a place where you can get all the information about the RS 2017 and I hope the RS 2019 is the same.
1) By PowerShell + WMI:
Get-WmiObject -namespace "root\Microsoft\SqlServer\ReportServer\RS_SSRS\V14" -class MSReportServer_Instance | Select-Object -Property EditionName, Version, InstanceName
Image-powerShellCommand
2) By C# + WMI (Do you will need to import the System.Management.dll)
using System;
using System.Management;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
ConnectionOptions options = new ConnectionOptions();
options.Impersonation = System.Management.ImpersonationLevel.Impersonate;
ManagementScope scope = new ManagementScope("Root\\Microsoft\\SqlServer\\ReportServer\\RS_SSRS\\V14", options);
scope.Connect();
//Query system for Operating System information
ObjectQuery query = new ObjectQuery("SELECT * FROM MSReportServer_Instance");
ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
ManagementObjectCollection queryCollection = searcher.Get();
foreach (ManagementObject m in queryCollection)
{
// Display the remote computer information
Console.WriteLine("EditionName : {0}", m["EditionName"]);
Console.WriteLine("EditionID : {0}", m["EditionID"]);
Console.WriteLine("InstanceID : {0}", m["InstanceID"]);
Console.WriteLine("InstanceName : {0}", m["InstanceName"]);
Console.WriteLine("Version : {0}", m["Version"]);
}
Console.ReadKey();
}
}
}

3) WMI:
wmi_1
wmi_2
wmi_3
wmi_4
Opening the WMI:
Namespace: Root >> Microsoft >> SqlServer >> ReportServer >> RS_SSRS >> V14
Class: MSReportServer_Instance
I hope I have helped with something
