By default, the Web Server is installed as part of the CommServe installation when IIS is enabled on the computer.
If you did not install the Web Server during the CommServe installation, or if you want to install additional Web Servers on other computers,
you can do so by using the installation package that was created from the Download Manager application.
How do you create the installation package for the web server, because I cannot select webserver. If i install the Command center ,the web server is not installed. I use 11.40.38.
My co-worker see the same issue.
