The located assembly’s manifest definition does not match the assembly reference

When running a real time map from CRM to GP, receiving the following error in a pop up window in CRM: “The located assembly’s manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)”

There are usually two items that may cause this issue.
The first item is if the maps have not been unregistered and reregistered on the new version.
To resolve this do the following:
1. Open the map up in SmartConnect. Click on the Register button.
2. Uncheck all the checkmarks and click on Process
3. After the window closes click on the Register button again
4. Check the events you want to register the map on and click the Process button
5. Save the map and close the Map Setup window.

The second item that can cause this is if IIS has not been restarted after upgrading to a new version of SmartConnect.
To resolve this do the following:
1. Restart IIS by going to Start – Run and type in “iisreset” in run command and click OK
2. A Command Prompt Window will open letting you know when the services have been restarted. The map should run successfully after making these two changes.
