What's FoxPro version?

>We are using a program called DZ_EASY.PRG that registers function in Dynazip using the Regfn32 function from Foxtools.
>
>I can get a consistent error 2028: API call caused an exception on windows 98 machines with the following lines at runtime:
>
>SET LIBRARY TO foxtools.fll
>IF "Visual FoxPro" $ VERSION()
> fdzipstart = RegFn32("dzipstart", "", "I", "DZ_EZ32.DLL")
>
>The error occurs on the last line above.
>
>The only library in memory is the foxtools.fll in the working directory.
>
>If I run foxpro, CD to the same directory, set library to the same file and run the command it works fine.
>
>We do not have the same issue on win 2000 machines.
