Code that runs fine in development may generate Appropriate license for this class not found (OLE error code 0x80040112) at run-time.

There are two types of licenses for ActiveX controls - development and run-time. See INFO: OLE Control Licensing in Visual FoxPro for more information.
When ActiveX control is instantiated with CREATEOBJECT()/NEWOBJECT() functions or ADDOBJECT()/NEWOBJECT() methods, the development license is used. However such license is only available on the PC where VFP is installed. Running the code on PC w/o VFP installed will generate Appropriate license for this class not found (OLE error code 0x80040112).
In order to provide a run-time license for an ActiveX control, the control has to be subclassed in a visual class library (.VCX) and subclass used in the CREATEOBJECT()/NEWOBJECT() functions or ADDOBJECT()/NEWOBJECT() methods.
