PROGMSG_IIS_ROLLBACKWEBSERVICEEXTENSIONS = Rolling back web service extensions

We have converted our installer project from IS 2016 to 2018. After that when I try run the installer I am getting below errors.

Property(S): PROGMSG_IIS_CREATEAPPPOOL = Creating application pool %s

complete log file attached. After going through the previous tickets on the same topic I could see that having read only attribute for web.config could be an issue. But in my project web.config has full permissions.

What you are listing are not necessarily errors, they are the Property dump at the end of the installation which lists all the values of all the Properties within the installer.
Just because a property has a string value of " Rolling back web service extensions" does not mean that the installation will rollback. It is just a Property value that is used "if" that does actually occur.

The end of your log file shows: 
MSI (c) (50:90) [12:06:03:579]: Note: 1: 1728
MSI (c) (50:90) [12:06:03:579]: Product: MySampleVRS -- Configuration completed successfully.

This tells us that the installation completed successfully without any issues, and searching your log for a "Return Value 3" (which is a failure) is not returning any problems.

Does your installation fail to install the necessary files? If so what behaviour do you actually see?

I have added a webservice extension and a virtual directory in installer server configuration. I am trying to install it on Windows 2019 server which has IIS 10 installed. 

When I run the installer with IIS6 compatibility setting enabled it is working fine and virtual directory is getting created in IIS where as if I run the installer with IIS 6 compatibility setting disabled, installer is rolling back and nothing is showing in IIS.
