Текст ошибки собственно такой:
Can not load 7-zip library or internal COM error! Message: DLL file does not exist.

перепробовал кучу всего уже и заносил sevenzipsharp.dll в C:WindowsSysWOW64, проверял так же на наличие повреждений,глухо всё, может кто знает в чём проблема?

Никитка98, насколько я понимаю необходимо положить рядом с программой 7z.dll из каталога с 7-zip. Или указать путь к нему перед началом работы

1	SevenZipExtractor.SetLibraryPath(@"C:Program Files7-Zip7z.dll");

Никитка98, что именно ты сделал? Положил библиотеку рядом с exe или установил путь из программы? Если второе, то путь верный? Вызов делается SetLibraryPath до обращения к другим методам библиотеки?

OwenGlendower, Пробовал и то, и то, путь конечно же проверил,писал так же относительный путь, но бестолку, да вызов делаю в начале программы:

            string arr = @"arhive/text.txt";
            SevenZipExtractor.SetLibraryPath(@"C:Program Files7-Zip7z.dll");
            SevenZipCompressor szc = new SevenZipCompressor();
            szc.ArchiveFormat = OutArchiveFormat.Zip;
            szc.CompressionMode = CompressionMode.Create;
            szc.CompressFiles("arhive/test2.zip", arr);

Hi all,

I am using SevenZipSharp component in my application (.net windows service) for extraction, SevenZipSharp requires 7z.dll which gets loaded at runtime. My application is working fine on my local machine but when on a 64-bit server where my application is running as 32-bit i am getting an error:

(1) When 64-bit 7z.dll is used then below exception is getting logged:

SevenZip.SevenZipLibraryException was caught
Message=»Can not load 7-zip library or internal COM error! Message: failed to load library.»
Source=»SevenZipSharp»
StackTrace:
at SevenZip.SevenZipLibraryManager.LoadLibrary(Object user, Enum format)
at SevenZip.SevenZipExtractor.Init(Stream stream, InArchiveFormat format)
at SevenZip.SevenZipExtractor..ctor(Stream archiveStream, InArchiveFormat format)

(2) when 32-bit 7z.dll is used then below exception:

Message: SevenZip.SevenZipLibraryException: Can not load 7-zip library or internal COM error! Message: can not change the library path because the file «C:Windowssystem327z.dll» does not exist.
   at SevenZip.SevenZipLibraryManager.SetLibraryPath(String libraryPath)

Please help in resolving this issue.

User Name or E-Mail Address:

Hello all. I have ran into a problem recently and have not been able to fix it. We recently updated to 6.2.0, but the task to export settings is failing with this error message:
Job Error: Exception in Task: Can not load 7-zip library or internal COM error! Message: Your 7-zip library does not support this archive type.

I have tried to uninstall and reinstall visualcron with no luck. I even installed 7-zip in a vain attempt to fix it.

I receive the same error message from manually backing up or using the task.

Can anyone help?

Forum information

Yes the file size is 0. I just sent the email

Yes, I suspected that. For some reason it is 0kB which generates this cryptic error (we will correct this in the future). The question is how this 0kB file was created.

Is your system critical to replace with a backup now?

If not, can you test running the Task again to see if it creates this 0 file again.

Every time I run the task, the 0 byte zip file is created.

I can probably restore the server from a backup this weekend, but that seems like an extreme fix for this problem. Or are you referring to restoring the visualcron settings?

I was just referring to the direct need for restoring the settings.

There is probably some kind of natural explanation for the zero byte file. First, please tell me about your settings (a screenshot from the Task would be great) and also try to export to a local path to see that it works.

I deleted everything off of the server including all settings. I installed a fresh copy, and am using the default task «Backup Settings»

I changed the path to the system default, and the C drive, and it is still exhibiting the same error.

Do you get any error in the file log_serverDATE.txt (log folder of installation)?

Yes I received the same error message manually running the export or running the export from the task

Please post screenshot with settings and tell me about your operative system and architecture (32 or 64 bit). Also, please confirm through Task manager if VisualCron runs as 32 or 64 bit.

All settings are default except for credentials

DieHardTekkie attached the following image(s):

Try running it locally without Credentials — does that work?

Unfortunately that does not work

Hello Henrik. Billy works for me. We have 10+ servers with VC on it, and this is the only one causing the issue and it started after 6.2.0 was installed.

So, to confirm VC uses 7-Zip for archiving?

And guess what?

6.1.9 works. I’m going to upgrade to 6.2.0 again to test.

Ok, scratch that. This does not work with 6.1.9. The VC does not indicate an error, but the zip files are 0-byte!

Yep, in the log even on 6.1.9:

«3/23/2013 6:44:22 PM Err Error when backuping files, err: Can not load 7-zip library or internal COM error! Message: Your 7-zip library does not support this archive type.»

We could not reproduce this on our test system. Could you please tell us more about operating system and if it is 32 or 64 bit?

Henrik please let me know what additional information you require. We can provide remote access into the machine if you need to check something. Do you have an uninstallation tool that we could run? Maybe a file or setting that was not removed when we uninstalled.

We are currently installing a new test machine. What we need to know:

1. operating system
2. architecture (32 or 64 bit)

1. Windows Server 2003
2. 32 bit

We installed a 32 bit Windows 2003 and upgraded it with SP2 and all services packs. We ran the default Export settings Task with success and it created a non-zero file. We tested this with version 6.1.9.

We assume this is related to one of these:

1. not having all updates installed (framework and service packs)
2. install is corrupt in some way (uninstall and re-install)
3. some settings (job, connection etc) causes an error during export
4. you do not have full access to the export location or VisualCron installation directory

If you zip the settings folder and send to support@visualcron.com we will be able to test with your exact settings which can rule out 3. Thank you.

I just sent you the file. Visualcron worked before the update. 6.2.0 installation broke visualcron.

1. The server is fully updated
2. I have uninstalled and reinstalled. Do you have an uninstallation tool that may do a better job at uninstalling?
3. Everything is DEFAULT. We have made no changes from the initial installation. All settings are unchanged
4. I have full access to all network paths in my domain.

Thank you for the file. Unfortunately we could not reproduce this. Can you test with latest 6.2.1. if you get same issue? http://neteject.com/down…Cron/VisualCron6.2.1.exe

No special uninstalling should be needed.

Хорошо, теперь я постараюсь объяснить свою проблему как можно больше. Я хочу использовать популярный алгоритм сжатия 7zip в моем проекте С#.

Пакет NuGet для 7zip уже есть.

Теперь, когда я устанавливаю страницу 7zip https://www.nuget.org/packages/SevenZipSharp/0.64 .0 он устанавливается нормально, но выдает ошибку, когда я пытаюсь запустить

An unhandled exception of type 'SevenZip.SevenZipLibraryException' occurred in SevenZipSharp.dll

Additional information: Can not load 7-zip library or internal COM error! Message: failed to load library

Поэтому я решил добавить файл DLL вручную, и я получаю эту ошибку ниже

    ---------------------------
Microsoft Visual Studio
---------------------------
A reference to 'D:51_doktora tez projesiprogram_crawlerdoktora_tez_projesi_crawler_programExternalDLLs7z_9_38_2015_01_03.dll' could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component.
---------------------------
OK   
---------------------------

Хорошо, но я нашел решение, и оно работает таким образом

Сначала установите пакет nuget

И перед тем, как начать вызывать функции, установите путь

SevenZip.SevenZipExtractor.SetLibraryPath("SevenZipSharp.dll");

SevenZip.SevenZipCompressor.SetLibraryPath("SevenZipSharp.dll");

Хорошо, второй вопрос, который также интересен

Я хотел использовать последнюю версию DLL-файла 7zip. Итак, загрузите его с официального сайта: https://sourceforge.net/projects/sevenzip. /файлы/7-Zip/9.38/

Скачал MSI, установил и получил 64-битный dll-файл. Однако, когда я пытаюсь сослаться на этот файл, происходит сбой с сообщением об ошибке выше: Please make sure that the file is accessible, and that it is a valid assembly or COM component.

Однако трюк снова работает

Я устанавливаю пакет NuGet 7zip. Затем перед вызовом функций я устанавливаю эти 2 строки кода, и он использует последнюю версию файла DLL.

SevenZip.SevenZipExtractor.SetLibraryPath("ExternalDLLs/7z_9_38_2015_01_03.dll");
            SevenZip.SevenZipCompressor.SetLibraryPath("ExternalDLLs/7z_9_38_2015_01_03.dll");

Поэтому я ищу ответы, почему все это происходит? Почему я не могу напрямую добавить в качестве ссылки файл DLL, хотя трюк работает?

Windows 8.1 64-разрядная версия, Visual Studio 2013, обновление 3, приложение WPF

Часть вашей проблемы, скорее всего, связана с тем фактом, что SevenZipSharp является просто оболочкой для 7z.dll, которая, насколько мне известно, является dll C++. На странице проекта для SevenZipSharp также упоминается, что можно использовать любую совместимую dll, которую необходимо указать:

Для работы SevenZipSharp требуется родная библиотека 7-zip. Вы можете указать путь к dll 7-zip (7z.dll, 7za.dll и т. д.) в LibraryManager.cs во время компиляции, в app.config или с помощью метода SetLibraryPath() во время выполнения. + «7z.dll» — это путь по умолчанию. Для 64-битных систем необходимо использовать 64-битные версии этих библиотек. 7-zip поставляется с 7z.dll, которая используется для всех операций архивирования (обычно это «Program Files7-Zip7z.dll»). 7za.dll — облегченная версия 7z.dll, поддерживает только архивы 7zip. Вы даже можете создать свою собственную библиотеку с нужными вам форматами из источников 7-zip. SevenZipSharp будет работать со всеми ними.
