Could not load file or assembly 'Microsoft.Owin, Version=2.1.0.0

Question:

I just manually updated Help Desk to current version and I'm now receiving a error when i try to load the web-page.

Could not load file or assembly 'Microsoft.Owin, Version=2.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)


Answer:

Your web.config is missing some important directives that were added later. Please either copy the entire "<runtime>" section from the downloaded web.config to your existing one, or simply run the SetupTool.exe from the /bin subfolder after upgrading - it will do everything for you.
