This was a fresh install. To fix Fix Wmi performance counters I read here  https://docs.microsoft.com/en-us/troubleshoot/windows-server/performance/rebuild-performance-counter-library-values

but now as per instructions in Windows install disc I did not get to see 

any i386 folder in Windows installation disc available to me. 

searched for perfc009.da_ 

Now I tried second thing editing registry values as explained on above link https://docs.microsoft.com/en-us/troubleshoot/windows-server/performance/rebuild-performance-counter-library-values

tried running 

 lodctr /r in system32 

and read here 

From the link "Cannot load Counter Name data..." error message appears when manually installing TMSMMainService.exe - Apex One (Mac) (trendmicro.com)

https://success.trendmicro.com/solution/000152298

but since I could not fix any thing so I I used revo uninstaller (trial version) to uninstall every thing because from control panel I was not able to uninstall.

This time again a fresh installation I tried

and another error

The following error has occurred:

The MOF compiler could not connect with the WMI server. This is either because of a semantic error such as an incompatibility with the existing WMI repository or an actual error such as the failure of the WMI server to start.

Installation succedded with failure in 

Database engine services

Client tools backward compatibility

all above failed at the end of installation

Then as suggested on this forum 

I had tried 

Rebuilding the counters:

     cd c:\windows\system32

     lodctr /R

     cd c:\windows\sysWOW64

     lodctr /R

I did not tried below 

Resyncing the counters with Windows Management Instrumentation (WMI):

     WINMGMT.EXE /RESYNCPERF

Stop and restart the Performance Logs and Alerts service. 

Stop and restart the Windows Management Instrumentation service.

Create a new Data Collector Set (do not use an existing Data Collector Set).

because I could not understand instructions.

searched on internet.

with this link https://www.thewindowsclub.com/how-to-repair-or-rebuild-the-wmi-repository-on-windows-10

I did

C:\Windows\system32>lodctr /R

Info: Successfully rebuilt performance counter setting from system backup store
C:\Windows\system32>winmgmt /verifyrepository
WMI repository is consistent

so it seems WMI repository is fine.

I however uninstalled all instance of SQL Server 2019 what ever I could see in Control Panel program and features.

Again started installing from scratch. I got validation error. While installing SQL server 2019 developer edition this  time. 

I now did following

1. Uninstall all SQL Server components you can using Control Panel -> Programs and Features

2. Backup the registry.

3. Delete the following keys in regedit:

--HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server

--HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer

4. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and delete all the sub-keys referencing SQL Server.

5. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and delete all the keys referencing SQL Server.

6. Deleted all the SQL Server folders in the computer C:\Program Files\Microsoft SQL Server and subfolders.

I started a fresh installation. Now I get following errors during installation

error 1
