After upgrading to Arcview 3.2, why is the message "Library C:\ESRI\Av_gis30\Arcview\bin32\IASrc.dll failed to load error 31" returned when I try to open a project created in Arcview 3.1?
IASrc.dll is an Image Analyst Extension dll file. The project was created with the Image Analyst Extension loaded and the dll file is not being read after upgrading to Arcview 3.2.
To resolve this, simply reinstall the Image Analyst.
