Problem: Invalid Raster Dataset/Raster data sources are broken in MXD

Description

Adding any raster produces the following error message:

"Invalid Raster Dataset"

When opening map documents that contain raster data sets, all data sources for the raster data sets are broken.

Cause

Another imaging application was installed on the computer that conflicts with the file rdo.dll.

Solution or Workaround

Re-register rdo.dll.

  1. Close all ArcGIS applications.
  2. Navigate to Start > Run.
  3. Type the following:

    Code:
    regsvr32 "C:\Program Files\Common Files\ESRI\Raster\bin\ntx86\rdo.dll"


  4. A message appears stating the registry of the dll succeeded. Click OK.

    Note:
    The above applies to Version 9.3.1 and earlier. The rdo.dll file does not exist in Version 10 and higher.
