Hi @tamilarasan l ,
1.The tool may not be able to download the required prerequisites before starting the installation. Make sure the server is connected to the network and the Internet is available. Connect the server to the internet and retry the installation.
2.Check if Windows Update Service is disabled, try to enable it and then configure IIS.
3.Use the PowerShell command Install-WindowsFeature to install the desired feature offline. Please go to the command line with administrator privileges and execute the following cdmlets, where "D:\sources\sxs" is replaced with the actual path of the source file. The source file is on your Windows Server 2019 installation media and you need to specify it for the prerequisite installation to work. Restart the server and use the wizard to install.

Remind: If you get an error during installation, you need to run it one by one to determine which function it fails on. This could happen for a number of reasons, and you might be able to share the error message. For example, if the error is returned: 0x80073701, it may be caused by the language pack, etc.
