Limitations of Runtime Mode Callable IDL Applications

IDL applications that run without an IDL development license — whether native IDL or Callable IDL — do not have access to the IDL compiler and thus cannot compile IDL source code from .pro files. As a result, operations that require the compiler will not execute when a development license is not present. In addition, if you are writing an IDL application to be distributed to users who do not have an IDL development license, you should be aware of the restrictions described in Limitations of Runtime Applications in Distributing Runtime Mode Applications.

Note
Startup files are not executed when you launch an IDL application without a command line. See Understanding When Startup Files are Not Executed (Using IDL) for details.
