The .zip files that my customers digitally download seem to be corrupt after download for some of them. I am able to use them on a XP machine as well as a Vista machine with no errors. Does anyone have any idea why they would work for me and others, but not for everyone? Any help is greatly appreciated. |

What're you creating them with? |

eBookGold Pro. I also thought that it might be the compression engine of the program, but once again I don't think that could be an issue for the fact that the files work on some machines, but not some others. |

can you customers having the issues even download zip files. Not sure if these are companies but, some companies block zip files. Ours do. So if I were to try to download a zip file, it would look like it downloaded but when I tried to extract it, it would be corrupt. So, I mostly have people send me tar files if possible. |

No these are individuals who are not behind any corporate firewall. There should not be anything blocking them from downloading .zip files. eBookGold Pro takes html files and makes them .exe eBooks. It allows me to protect the data that I sell, i.e. no printing, print screen, copy and paste, or anything that allows duplication. |

Have you checked so that the files are not served as text and as a result getting corrupted by platform newline normalisation? It's happened me a few times with zip-files. |

Ok, so some customers receive 'good' zips, and other's don't? |

I have finally figured out a solution. From what my customers have told me the error arises when trying to open the file using the built in XP zip program. You know, the one that takes .zip files and automatically allows users to open them without using an outside program. To avoid this issue I have just told customers that they must use WinRar to extract the files. Not the most convenient approach, but one that seems to work for them. |
