Perhaps you can recompile it again too since you have Framework 3.5 and post another (separate) version with the comment in Downloads?

>>Hello Gregory,

>>We've been using your vfp.fll callback routine for some time now to implement a progress bar when using a zipping dll. However, our wrapper routine now crashes when I run it from my station. The routine works fine for everyone else.

>>The only thing I can think of that accounts for the difference is that I have loaded Visual Studio 2008 on my machine. I'm wondering if this has updated some sort of external C dependancies that keep vfp.fll from running on my machine.

set library to vfp.fll additive

>>The error message that I receive is that the library vfp.fll is invalid.

>>Thanks for whatever help you can offer.

>(1) dependency walker - as suggested
