sql script error - Invoke-ServerInventorySQLBuild.ps1 about serverinventoryreport HOT 1 OPEN

I got following error with "Invoke-ServerInventorySQLBuild.ps1" sql express is installed in same server
ERROR*****************
Invoke-SQLCmd : Exception calling "Open" with "0" argument(s): "A network-related or instance-specific error occurred
while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the
instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes
Provider, error: 40 - Could not open a connection to SQL Server)

I found the solution-
1.Check that TCP/IP and Named Pipes are enabled, in my case it was disabled
2.When you specify server name in script also add instance name, if you created one already during sql server installation.
