I am working with a new installation of ArcGIS desktop (with a 30-seat arcinfo license). I can use ArcMAP, but ArcGIS Online does not appear in the File menu, nor does it appear in the Add Data pull down menu. Is something wrong with the installation, or is there a simple thing I'm missing?
You might want to check the ArcGIS Administrator application to see if the www.arcgis.com appears. From All Programs>ArcGIS>ArcGIS Administrator. Click the Advanced button. Then click Manage Portal Connections. Do you see http://www.arcgis.com listed? This is what points ArcMap at arcgis.com.
You may want to contact Esri technical support as they are better equiped to troubleshoot this issue.
Thanks,
Mike
