Today I faced a strange issue when I tried to install a new SQL Server instance : Failed to retrieve data for this request
This error occurred just after clicking on “New SQL Server stand-alone installation…”

The error message is not helpful at all. So, the first step to troubleshoot an issue is to look at the error logs.

The location by default is : C:\Program Files\Microsoft SQL Server\140\Setup Bootstrap\Log
There is a summary.txt file and many subfolders created every time the Installation wizard is started. In those subfolders, we can find a Detail.txt file.

The error looks like this:

Exception type: Microsoft.SqlServer.Management.Sdk.Sfc.EnumeratorException
        Failed to retrieve data for this request.
    HResult : 0x80131500
      HelpLink.ProdName = Microsoft SQL Server

                The network path was not found.
        HResult : 0x84d10035
                FacilityCode : 1233 (4d1)
                ErrorCode : 53 (0035)

The useful information here is the message about network: The network path was not found.
I try to install the instance on a server that is a member of a Failover Cluster. So this gives me a hint.
I need to check any connectivity issue between the 2 nodes of my cluster.

The 2 nodes can ping each other. The DNS resolution is fine.
Out of curiously, I tried the administrative shares and it was not working from my current server to the other node. The other way around is fine. This is surprising and I tried to fix this.

Without further ado, I will show you where the issue comes from.

Someone had disabled File and Printer Sharing for Microsoft Networks on the Ethernet Adapter of the other cluster node.

Enabling it made both the administrative shares and the SQL Server Wizard behave as expected.

I hope this was helpful if you encountered the same error message when trying to install an SQL Server instance in a Failover Cluster context.
