Can't load toolbox model to the ArcMap 10.1 & drag-drop problem

[Nik_Mohd_FadhilNik_Mohd_Kamil]

Hi folks,

Our GIS server is already upgraded to the ArcGIS 10.1 SP1 from ArcGIS 10.0.

When I tried to add existing toolbox model (created from ArcGIS 10.0) to the new ArcMap table of content, the Warning "A selected item could not be added to the Map" is popup.

I also noticed that drag-drop item from Arcmap 10.1 catalog to the TOC is not functioning.

Anybody know how to get around this? I tried make a new model on ArcMap 10.1 SP, but it also failed to be added into the map.

Help me!

See the Help topic "Tool layers based on your model and script tools":
http://resources.arcgis.com/en/help/main/10.1/index.html#/Tool_layers_based_on_your_model_and_script...
"The capability to create a tool layer was removed at version 10.1. Tool layers in ArcMap documents created prior to version 10.1 can still be used in 10.1."
From this information, you won't be able to add tool layers to a map in 10.1.
