The application has installed fine thus far. But switching url names from http to https in the manifest seems to break the installation. There shouldn't be a problem with the certificates but I get the following exceptions:

(System.Net)
The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

(Inner exception - System.Security.Authentication.AuthenticationException)
The remote certificate is invalid according to the validation procedure

Any advice?
