ERM009: Could not get value IMAGINE_HOME under the HKLM registry key: SOFTWARE\ESRI\Raster\Environment

Error Message

During the install or uninstall of the ER Mapper ECW plug-in, the following message is displayed:

"ERM009: Could not get value IMAGINE_HOME under the HKLM registry key: SOFTWARE\ESRI\Raster\Environment.
Please refer to the readme.txt and contact support."

Cause

The ECW plug-in install and removal requires registry keys which are no longer present or created by ArcGIS 9.2.

Solution or Workaround

Note:
ArcGIS 9.2 natively supports ECW reading and also compresses images with JP2 compression. The ECW plug-in is no longer required to perform these functions in ArcGIS 9.2.
