I am currently trying to implement the Interop.MODI.dll (From Microsoft Office) to use the Image -> Text features it should Provide.
But when doing

var modi = new MODI.DocumentClass();

I get:

“COMException 80040154 with CLSID {40942A6C-1520-4132-BDF8-BDC1F71F547B}”.

What have I tried to solve that problem?

I registered the DLL using the regasm tool:
-Problem still exists

I tried setting the BuildPlatform to x86:
-Problem still exists

I use the Visual Studio 2010 Ultimate with Windows 7 Professional 64Bit & Have Microsoft Office 2007 installed

EDIT: I found the Solution:

I needed to install the “MS-Office-Document-Imaging” feature to MS
Office to get it working. (Software -> MS Office (rightclick -> edit)
-> Add Features -> Microsoft Office Document Imaging)

    Try to check if Microsoft Office Document Imaging Components are installed correctly.

    You can do that by modifying your Microsoft Office Installation

    Software > Edit Microsoft Office Installation > Add/Remove Components.
    Be sure, that Office-Tools > Microsoft office Document Imaging is installed completely!

    Furthermore, if you are developing on a 64-bit machine, change your project output from any CPU to x86
