Hello,

I have an application in FoxPro 2.6 (Windows) that launches an executable in Visual FoxPro:

! /N PreviewForm.exe

Now this would cause an error if the VFP libraries are not installed on that computer.
Instead it would be nice to display a message that the user needs to install those libraries before using this functionality.

But how can I find out from FoxPro 2.6 whether the VFP9 libraries are installed?

My guess would be to use RegFN and CallFn, using a 16 bit dll, but I am not at all familiar with 16bit dlls.
