While installing SQL Server 2017 Developer Edition, I got stuck at
Install_SQLSupport_CPU64_Action
,this happened to me for the second time, once at work and once at home.
The solution: You will need to browse to this installation path:
C:\SQLServer2017Media\<YOUR_SQL_ENU>\1033_ENU_LP\x64\Setup
Then while the setup is stuck at
Install_SQLSupport_CPU64_Action
run SQLSUPPORT.msi
And follow the installation procedure.
Once installed, run the following command in cmd:
taskkill /F /FI "SERVICES eq msiserver"
The SQL Server setup will continue and succeed.
