I managed to get a new VC 2.5 installation finished, but the VMware Update Manager won't install. I get the error "Error 25085.Setup VMware Update Manager extension to VMware Virtual Center Server: <server IP>". Then it fails with "Warning 25015.VMware Update Manager could not be installed." There's no indication of why it won't install.
I also can't get the VMware Converter Enterprise for Virtual Center to install. The error is: "Error 25085.Failed to to register the extension."
Anyone know what's wrong here?
