Attempting to use the Dissolve tool in the ArcMap GeoProcessing wizard causes ArcMap to crash.
The layer being dissolved may contain records that have no geometry; that is, the records may contain values for other attributes, but the value for the shape field is empty or null. Trying to dissolve on such a layer will cause ArcMap to error.
Determine which records have no geometry, and delete these records from the layer. In order to preserve the original state of your layer, you may want to make a copy of it and perform these steps on the copy.
Make sure all your features are visible.
