WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

If you launch the forecasting tool directly from Contact Center Client, this function will work properly. 

CAUSE

A pair of .DLL files needed are missing from the WFS folder, but present in the Contact Center Client. 

RESOLUTION

You will need to copy two files.

1. Go to [InstallDir]\Applications\ContactCenterClient\.
2. Copy the syncfusion.grid.grouping.windows.dll and syncfusion.grouping.base.dll files. 
3. Paste these files into [InstallDir]\Applications\CcsClient\.
4. Re-launch the WFS application.
