SYMPTOMS

Consider the following scenario:
  • You install the 64-bit version of Microsoft InfoPath 2010.
  • You create a Windows Forms project in Microsoft Visual Studio.
  • You add an InfoPath FormControl control to the toolbox.
  • You insert the FormControl control on the Windows form.
In this scenario, you receive the following error message:
Failed to create component 'FormControl'. The error message follows:

WORKAROUND

There is no workaround for this issue when you use the 64-bit version of InfoPath 2010. To use the InfoPath FormControl control, install the 32-bit version of InfoPath 2010.
