Hello ~ I still have /use DataEase 4.53. I have downloaded De5.53 from your Web Site. I am unable to unzip it. What program was used to "Zip" the file? I have tried various programs with no luck. Thank You for your consideration in this matter. Sincerely; David 

Dear David Lupp.

I don’t think we have any DFD for “official” download anymore on our website ;-)

But I checked the un-official link and the file is zipped with normal zip i.e. I can unzip it automatically as a zipped catalogue in Windows.
