Re: ZipException: invalid entry CRC on opening the sh3d file what did you do though? I just opened it, then I've selected File->Save as. Are you able to create a new file, save it, and open it back without getting errors? Maybe you have updated your JDK and the new version has a different/bad zip implementation. You could try to start SH3D pointing to a different JDK. Anyway, don't worry, your files aren't corrupted :) |

Re: ZipException: invalid entry CRC on opening the sh3d file Wile You are under linux I recommend You to use the official version from this site (forget the repository versions ) Eventually read this post After that I'll be able to help You. Anyway Your file 3UrP maybe need a extension like sh3d or zip or tgz ---------------------------------------- A computer program does what you tell it to do, not what you want it to do. Murphy's Law When all else fails, read the instructions. Murphy's Law If you don't like "AS IS", DIY. Dorin's law |

Re: ZipException: invalid entry CRC on opening the sh3d file Daniels, huh, unexpectedly Im not able to do so - i just tried that twice I did not update java since I installed sweethome3d - and it flawlessly worked before (opening and saving) I dont know what could have caused the now permanent misbehaviour - is there some debugging function ? As said, the repository version can not be the problem here - it worked before (no changes in java/sweethome packages happened). |

Re: ZipException: invalid entry CRC on opening the sh3d file i tried openjre8 11 and 17 - all yield the same result however I can load the demos |

Re: ZipException: invalid entry CRC on opening the sh3d file however I can load the demos This isn't so weird since demos are embedded within the jars, so as long the application starts it will always be able to load the demos. It could be that the JDKs use some native system call to handle compressed files (but not the jars), so a system update or other software installation could affect the JVM behaviour. Have you update your OS or any other application? |

Re: ZipException: invalid entry CRC on opening the sh3d file yes I updated several packages like kernel and libzip but as I can uncompress the files outside sweethome3d I wouldnt suspect a problem with external packages explicitly the crc checksum error would have to occur if it was system issue |

Re: ZipException: invalid entry CRC on opening the sh3d file Sorry, but I have to contradict you :) There are 2 ways a zip can be opened: - as a file, meaning a determined amount of data, which you can access randomly; - as a stream, meaning a flow of data which you can read only sequentially. SH3D uses the latter (ZipInputStream is mentioned in the stacktrace). It is well(?) know that this way of opening zip files may cause problems... I won't report the details here, but you if you are interested you can learn more here: https://commons.apache.org/proper/commons-compress/zip.html So you may try rollback the libzip upgrade. This isn't a solution, but if we can identify the bug we can find a workaround and possibily fix it in the future. Please also post the version of the libzip you're using. |

Re: ZipException: invalid entry CRC on opening the sh3d file I would not have thought that did the trick apparently |
