ArcGIS Engine Developer Guide

APPLICATION DEVELOPMENT AND LICENSE INITIALIZATION
The checkout of licenses may fail even though
the availability check was successful. This is
particularly possible in cases where Desktop
Concurrent licenses were initially available but
may have since been checked out by another
application.
1. Check whether the Network extension is already checked out. If the license is
checked out, the application can use the Network functionality. If the license
is not checked out, check the license out.
2. Check out the Network extension. If the license failed to check out, then the
application cannot use the Network functionality. If the license is checked
out, the application can use the Network extension.
After developing a custom standalone application, it should be tested with
ArcGIS Engine Runtime before it is deployed to end user machines. Supplied as
part of the ArcGIS Engine Developer Kit is a redistributable version of the
ArcGIS Engine Runtime and registration numbers for the runtime testing of
custom applications.
