I have a code with toolbars which I tried to run it in another PC but it failed. I get a run time error "Method Addtoolbox of object I GDispatch failed". The line that the code stacks is the last one shown below. Could you help me please? I work with ArcGIS 9.3 in VBA. Thanks Dim GP As Object Set GP = CreateObject("esriGeoprocessing.GpDispatch.1") ''''' 'Set the toolbox GP.AddToolbox "C:/Program Files /ArcGIS/ArcToolbox/Toolboxes/Conversion Tools.tbx"
