| Author | Forum: PowerTCP Zip Compression for .NET Topic: Upgrade from 1.1.1.0 to 1.1.3.0 now throws exception |

posted July 23, 2007 8:11 AM We have been using your product with no issues for the last 18 months before we had problems with zip files > 4gb. We recently upgraded to 1.1.3.0 as this includes the fix, however I am now unable to open any files that were zipped previously with the older version and I am getting an exception when calling Archive.Open(stream); The exception says 'Source array was not long enough. Check srcIndex and length, and the array's lower bounds'. If I try and unzip a file that was zipped up using the new 1.1.3 library I have no problems. Any ideas? Thanks :-) |

posted July 23, 2007 8:24 AM I used an older version of the program and tried to unzip something created with the newer version which uses 1.1.3.0. The unzip fails and the exception message this time says 'The zip archive is marked as a WinZip AES encryption format but it has some invalid data'. Hope this adds more light onto the subject!! |

posted July 24, 2007 1:01 PM Hi! Can you please provide exact steps to reproduce this? We have tried creating Zip files from last build - 1.1.2.0 and they unzip fine with new build - 1.1.3.0 Also provide the old build that you are using. Thanks, Raj |

posted July 24, 2007 4:43 PM I tried using 1.1.1.0, 1.1.2.0 and 1.1.3.0 builds and zipped files from the "ZipManager" sample for each version. The zip files created from all the above 3 versions were extractable from each other without any issues. I would need exact steps to reproduce this and work further. Thanks! Raj |
