PROBLEM
When installing ArcGIS, the installation may 'freeze' or stop responding while registering the file rastersde8x.dll.
Note: This article pertains to ArcGIS versions 9.x only. Later versions of ArcGIS may contain different functionality, as well as different names and locations for menus, commands and geoprocessing tools.
There are conflicting entries present in the registry.
After removing any ArcGIS products, and before attempting to install ArcGIS, remove the conflicting Raster entries in the registry.
