>thanks I get it from the help but there is one thing which the screen for winzip license agreement always it works automatecly can it be removed ?

You will have this problem on all machines that do not have WinZip registered. If you want to avoid this either register a copy of WinZip for every machine it is needed on OR buy a license for DynaZip and you can distribute the libraries unlimited and royalty free.

If you go with DynaZip, you can download and use my free DynaZip class for VFP.
