Error when Opening InfoPath form in Sharepoint

[AFalcon]

Hello All:

I get the following error when I try to open an InfoPath form:

The required application may not be installed properly, or the requested
document cannot be opened. Please ensure that the necessary application is
installed and that the path to the document is correct. If the application
was set to install on first use, run the application and then try editing a
document again.

InfoPath is installed. Is there any reason why this would occur.

Thanks in advance
