I believe this is a known issue that support is working on as we speak. From what I know of the problem it involes IIS being installed but the .NET components on IIS are not installed. These are the Windows Installed Components and not the actual .NET applications. I believe the work around is to either disable IIS on the Vista machine or enable .NET for IIS.
To summarize...I think the install application for the remote console is checking the Windows Installed Components and not the actual applications. A remote console doesn't need IIS as well.
