Note This object model member is not supported when the Disable Service Pack features option on the Advanced tab of the Options dialog box in InfoPath is selected or when Microsoft Office 2003 Service Pack 1 or later is not installed.

## Example

In the following Visual Basic for Applications (VBA) example, the UnregisterSolution method of the Application object is used to uninstall a form template:

    Public Sub UninstallForm()

       Dim objIP As Object

       ' Create a reference to the ExternalApplication object.
       Set objIP = CreateObject("InfoPath.Application")

       ' Unregister the InfoPath form template.
       objIP.UnregisterSolution ("C:\\My Forms\\MyFormTemplate.xsn")
       MsgBox ("The InfoPath form template has been unregistered.")

       Set objIP = Nothing

    End Sub
