Set the .NET Temporary Folder Permission

If the .NET framework was pre-existing on the IIS server (i.e., if it was already installed and not installed via the XFRACAS installation), you may encounter a server error the first time you attempt to access the website (e.g., “Could not load file or assembly ‘DevExpress.Charts.v16.1.Core’ or one of its dependencies. Access is denied.”).

If this happens, you will need to give full permissions for the .NET temporary folder (C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.Net Files\) to the account that XFRACAS runs as (specified in the XFRACAS configuration file). You may need to take ownership of this folder before you are able to do this.
