Hello All ,
I'm not able to complete SCOM 2019 installation in one of my lab environments. I have 2 lab environment and one was a successful install using the same set up files.
The installation page seems to get stuck on the " Importing system Network Management Management Pack" message. It does not proceed beyond this point and eventually fails.
Please advise

I have added the account which i'm using to run in the Administrator groups in the server. Added the account in the SQL log in and provided sysadmin permissions. 1 Management server and 2 DB servers for DB and DW . Please find the error logs from the setup wizard logs
