What version of ASP.NET should be configured for the IIS Application Pool running the RSA Archer application?

ASP.NET 1.1 is an outdated runtime that lacks the framework libraries and features that RSA Archer requires to operate.

ASP.NET 2.0 does not include the .NET 4.0 runtime capabilities that RSA Archer depends on for its application components.

ASP.NET 3.5 is not sufficient for RSA Archer because the application explicitly requires the .NET 4.0 framework, not the 3.5 runtime.

RSA Archer's web application layer depends on .NET Framework 4.0 runtime features and APIs, so the IIS Application Pool must be set to ASP.NET 4.0 to load and execute the application correctly. Configuring any lower version causes runtime initialization failures because the required framework components are not available in earlier releases.
