Notes

For GN4 versions 2.1 or newer, the .NET Framework 4.5.1 is required.

For GN4 versions 2.0, the .NET Framework 4.5 is required.

For GN4 versions 1.6 or newer, the .NET Framework 4.5 is recommended.

In the IIS Manager, select your server name (on the following screenshot it's BRUNONB), and then locate the ISAPI and CGI Restrictions icon in the IIS group.

Double-click the ISAPI and CGI Restrictions icon to display the list of allowed or denied items, and make sure that all instances of ASP.NET v4.x.xxxxx are set as Allowed. If not, double-click the item, and then select Allow extension path to execute.

Note

When installing any version of Framework, it may happen that ASP.NET for v4.0 appears to be missing although the installation steps were all correct. You will notice the problem only when trying to start GN4 and it fails.

In such case, perform the command:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe –ir

This will fix the problem.
