Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.237
ROOT CAUSE:
Knowledgebase version 9.0.2 utilizes Microsoft.NET versions 1.1, 1.1 SP1, 2.0, 3.5, and 4.0. This error occurs if version 4.0 is not the registered version (which can happen if it is not the last version installed, or if IIS is installed after the .NET components).
Per Microsoft documentation: "This error can occur when IIS is installed after installing .NET Framework 4, or if the 3.0 version of the WCF Http Activation module is installed after installing IIS and .NET Framework 4."
SOLUTION OR WORK AROUND:
To resolve this issue, it is necessary to re-register Microsoft .NET version 4.0. Per Microsoft documentation: "To resolve this problem, you must use the ASP.NET IIS Registration Tool (Aspnet_regiis.exe,) to register the correct version of ASP.NET. This can be accomplished by using the –iru parameters when running aspnet_regiis.exe as follows:
aspnet_regiis.exe -iru"
Alternately, (for example if lacking the aspnet_regiis.exe executable), this issue may also be resolved by performing a repair installation of Microsoft.NET version 4.0.
