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.
After searching online I found no solution.
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.
Edit:
2019 : C:\SQL2019...
2022 : C:\SQL2022\Developer_ENU\1033_ENU_LP\x64\Setup
if the error code is 0x851a001a, then you need to change the sector size of the hard drives. Here is the guideline for that.
