Question / Problem

Server Error '/' in Application. Could not load file or assembly 'System.Web.Mvc'...

Answer / Solution

The physical path is invalid. Set the physical path of the website to the installation folder of SpaceObServer Web Access:

1. Start the IIS-Manager (inetmgr).
2. In the left pane, navigate to Sites > SpaceObServer Web Access.
3. In the right pane, select 'Advanced Settings'.
4. Set the value of the 'Physical Path' to the installation path of SpaceObServer Web Access. The installation path is 'C:\Program Files\JAM Software\SpaceObServer Web Access' by default.
5. A restart of the website or a 'recycle' of the application pool is not required. Just open SpaceObServer Web Access in the browser again.
