000732: <value>: Dataset <value> does not exist or is not supported.


The tool was unable to open your dataset.

There are several reasons that could prevent a tool from opening a particular dataset. Most fall into one of these categories:

  • The tool could not find the data because the input data path was typed incorrectly or does not exist.
  • The data is in an unsupported data format.
  • The data is not supported by this particular tool.


Check the data path used to make sure it exists and can be accessed by ArcGIS. Correct as required and run the tool again.

If the data does exist, one of the following situations may have occurred:

  • 64-bit processing does not support some data formats. Use another format.

  • An invalid subtype on the dataset. To fix this, go to the feature class properties, click the Subtypes tab, and reenter the default subtype code. If the default is 0, click the cell with 0 and reenter that same value. Apply the change by clicking OK. You will now be able to use the dataset.
  • In ArcGIS Engine for Linux, a text file cannot be used as an input to a tool with an input table parameter, such as Copy Rows or Make XY Event Layer. On Windows you can convert the file to another format using the Table To Table tool.
  • The Register As Versioned and Unregister As Versioned tools cannot run against a controller dataset, such as a Geometric Network, Topology, Network Dataset, or Terrain. To fix this, run these tools against the feature dataset that contains the Geometric Network, Topology, Network Dataset, or Terrain.
