Hello. I can try to use TZipMaster component inside dll. When I need to zip some files I do: ZipMaster1:=TZipMaster.Create(nil); (Have not owner component inside dll) ZipMaster1.Load_Zip_Dll; ZipMaster1.FSpecArgs.Assign(TmpList); (TmpList exists and contains file names) ZipMaster1.AddOptions:=[AddUpdate]; ZipMaster1.ZipFileName:='C:\test.zip'; ZipMaster1.Add; ZipMaster1.Unload_Zip_Dll; ZipMaster1.Free; There are not test.zip at disk C. When I use the same code inside application all work OK. Thank you.
