Error: ArcGISFMEDataSource: Error in FMEDataSourceUtils::Session

Error Message

The following error may occur when starting ArcMap:

Error:   
ArcGISFMEDataSource:
Error in FMEDataSourceUtils::Session

Cause

A customization installed by Safe Software's FME Suite 2003X2 cannot find a license. This can occur even if the FME Suite was removed, because the uninstall procedure sometimes fails to properly unregister the custom .dll file.

Solution or Workaround

Either register or renew the licensing for the FME extension for ArcGIS or unregister the FME extension's dll.

  • Option 1: Register or renew the FME Suite by contacting Safe Software. See the Related Information.
  • Option 2: Unregister the <FME_HOME>\application_extenders\arcgis\ArcGISFMEDataSource.dll.
  1. Start up a command prompt:
    1. ​Click Start > Run > type cmd.
    2. Click OK.
  2. In the command prompt, type regsvr32 /u <path>\ArcGISFMEDataSource.dll
Note:
<path> is the path to this file. By default, the file is located in \application_extenders\arcgis\ArcGISFMEDataSource.dll.
