I'm trying to install .Net 2.0 Framework Service Pack 2 on a Win 2k8 server which currently has .Net Framework 2.0 SP1, .Net Framework 3.0 SP 2 and .Net Framework 3.5 SP1 installed. When I try to run it the installer immediately ends and displays a screen with Setup Error. No other information is shown. If I check the event viewer it shows a single related Information entry saying “Product: Microsoft .NET Framework 2.0 SP2 -- Installation completed successfully.” Having checked the Installed Updates/Programs I know this is not the case.
Any ideas what could cause this or how to debug?
