Microsoft office interop word dll

I got the sources of a .NET project that I am trying to compile. Although, the project uses the reference (namespace) Microsoft.Office.Interop.Word from Office 2010 that I cannot find anywhere.
I was able to download the file microsoft.office.interop.word.dll but apparently the one from Office 2007 since it still doesn’t compile because the project uses the function Document.SaveAs2 (which is from Office 2010 library).
I have Office 2007 on my computer and Visual Studio 2012 Express for Desktop.

Could you please explain me how this works? How come was I able to download the dll but I cannot find the one from Office 2010. How come my client was able to compile the projet without this dll? Does Visual Studio automatically «connects» to the Microsoft Office libraries if installed when compiling ?

Thank you for your help.

You shouldn’t be searching for the dll on your local system yourself if you installed the assemblies correctly. See following link for information on how to download and install office interop libraries without installing office. Second link details how to add the assemblies to your project correctly.

Install Office Primary Interop Assemblies

For a further reference here are some pictures detailing how to add the dll correctly:

In your project, right-click on «References» and select «Add» and then «Reference».

Add References

Next select «Extensions» in the Reference Manager, scroll to find the correct dll. Which for Microsoft.Office.Interop.Word.dll Office 2010 is the version 14 one.

Now that Visual Studio 2019 is out, you can install Microsoft Office interop libraries as part of an optional bundled component called Visual Studio Tools for Office (VSTO).

Microsoft have made this super easier, and you don’t need to reference them in the GAC!

Первым делом:

Скачайте библиотеку — скачать microsoft.office.interop.word.dll

Затем:

Поместите microsoft.office.interop.word.dll
в одну из следующих папок:

Если у вас 64-битная версия Windows, то поместите файл в:

«C:WindowsSysWOW64»

Если у вас 32-битная версия Windows, то поместите файл в:

«C:WindowsSystem32»

После этого

Перезагрузите компьютер, чтобы изменения вступили в силу.

Всё равно выдаёт ошибку microsoft.office.interop.word.dll
не был найден?

Тогда придётся установить этот файл вручную. Для этого:

Зайдите в меню «Пуск».

В строчке поиска введите «cmd». И запустите найденную программу от имени администратора.

В открывшемся окне введите «regsvr32 microsoft.office.interop.word.dll
«.

После этого снова перезагрузите компьютер. Теперь ошибка должна быть исправлена.

Если что-то не понятно прочитайте более подробную инструкцию — как установить dll файл.

    Hi,

    I am almost ready to put my next app on the web… Word reports are a big part of it…

    But the current webhost does not have/want to install word/office files on server.(GAC…)

    Is it possible to just include a Microsoft.Office.Interop.Word.dll in my BIN folder?

    If so, where can I find that file? (link anyone? I do not want O2003PIA.exe installation, JUST THE DLL !? can’t find it anywhere)

    Regards,

    NNM

    I’m not sure — A moderator could probably answer you better; as they may have information they can directly access but here’s my guess.

    The dll is licensed with the product — you’re allowed to use the dll with the product, or for «extensibility» with the product (in this case office).  I would seriously doubt you are allowed to redistribute that dll to your web application — on a host
    that doesnt have that product installed.  If word reports are a big part of your application, then you are basically saying that the «System Requirments» include needing word installed, so you have the dll in the GAC.

    Of course this is just a guess, but my feeling is — you may need another solution, you obviously dont want anywhere you host it, to have to install word just to run you’re web application…maybe you do.

    As you mentioned…you’re other option is to install the Microsoft Primary Interop Assemblies — which are available for download for this reason.

    http://msdn.microsoft.com/en-us/library/aa159923(office.11).aspx

    You can find information about it at that link.

    Hi

    Did you find solution for that.

    I am facing the same problem, and I do not know if I am allowed to distribute the dll with my application.

    Thanks

    I have no idea if you can or not…

    In my case, I just made a vb class that doesn’t require any server side dll files.

    Two, actually: one for office2003+ (write in wordml) or old versions (write in html)..

    Downside: client (user) has to have office on his computer.

  • User-1789103342 posted

    open a new test project.

    In your solution explorer right click on the project name > click on Add Reference > .Net Tab > Select «Microsoft.Office.Interop.Word» (version 11 for 2003) and say ok

    Open a new file and type

    Imports Microsoft.Office.Interop.Word

    It should work

  • User1075616431 posted

    But is it (legally) allowed?

    It gives your application the power to generate MS word documents.. Does it need it’s own license, or..?!

  • User-1386145889 posted

    It only gives your application the power to talk to an existing MS Word installation to generate documents.  You need to have a licensed copy of MS Word installed on any computer you want this to work for.

About Microsoft.Office.Interop.Word.dll Errors

When you use a program on your computer, it may need to use a specific file called «Microsoft.Office.Interop.Word.dll». This .dll file contains important instructions that the program needs to work correctly.

When you open the program, your computer will look in two specific places to find the .dll file. First, it will look in the folder where the program is installed on your computer. Second, it will look in a system folder on your computer called «System32» and/or «SysWOW64».

If your computer cannot find the «Microsoft.Office.Interop.Word.dll» file in either of these two places, you may see an error message that says the file is missing. This can cause the program to not work properly or to not open at all.
