Can't install creatio

Hi,

I have 2 VMs for Creatio v8.0.8.4807:

1 on Windows Server 2016 wirh iis where located all Creatio files

2 on Ubuntu 20 with Postgres 12 + Redis

So after all installation steps i face with a problem 

Config Error   The configuration section 'terrasoft' cannot be read because it is missing a section declaration

Config File   \\?\C:\inetpub\wwwroot\8.0.8.4807_ServiceEnterprise_Softkey_PostgreSQL_ENU\Terrasoft.WebApp\web.config

I have checked web.config and ConnectionString and all seems fine

Also attached the error screen and in rar format web.config + ConnectionString



Thanks in advance
