Cause
This error message is caused by ASP.Net not being registered correctly with IIS and not appearing in the Application Pools, the screenshot below outlines an expected configuration, in this example ASP.Net 4.0 is used and correctly registered and appears in the Application Pools.
Resolution
To resolve the issue ensure the version of ASP.Net used on the machine where FlexNet Manager has been installed on is correctly registered with IIS.
The following command can be used to register .NET 4.0, if a different version of .NET is installed on the machine please consult the FNMS Install Guide in the "Configure IIS" section.
1: Open an Administrator command prompt and browse to the following directory "%SystemRoot%\Microsoft.NET\Framework\v4.0.30319", the 32 bit version needs to be used.
