I've tried to use ./build.sh windows2008 and got the error:

Exception setting "SecurityProtocol": "Cannot convert null to type "System.Net.SecurityProtocolType" due to invalid enumeration values. Specify one of the following enumeration values and try again. The possible enumeration values are "Ssl3, Tls"."

It means that dotnet 4.5 wasn't installed (because this package supposes to do this). I investigated it a bit and found the error:

2022-11-02T22:59:41 System.Management.Automation.MethodInvocationException: Exception calling "DownloadFile" with "2" argument(s): "The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel." ---> System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.

The entire log file: https://gist.github.com/DevelopMan/fdd9e5356452598c7a691f08615847b0

The script can't download the dotnet package because of the certificate.
