I was setting up a VPC today and during the checks I got the following error:
"ASP.NET 2.0 is not installed"
Very weird. I had it installed and I tried repairing the installation and running aspnet_regiis -i on the ASP.NET 2.0 framework. After some googling I found that this was due to Microsoft .NET Framework 4.0 installed and this excellent blog explaining what was wrong and how to fix it. I did, however, have to remove the ISAPI filter for .NET Framework 4.0. Check it out here:
