The following error may occur during the deployment of a MapObjects application:
aiimage20.dll failed to register
This error often occurs because all image components (DLLs) were not deployed into the same directory. The MapObjects documentation recommends that all image components be installed into the Common Files\ESRI folder.
Some of the image DLLs are versioned and some are not. By default, the Visual Basic Package & Deployment Wizard will install versioned image components into Common Files\ESRI and will install non-versioned image components into the application's path (AppPath).
