  • 0

I made a WPF/C# program and I am using the internet control for WYSIWYG HTML editing.

it is a regular Executable program.

it works on most computers however some computers are giving me the following error.

Could not load file or assembly
‘Microsoft.mshtml, Version=7.0.3300.0,
Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a’ or
one of its dependencies. Strong name
validation failed.

The ‘Microsoft.mshtml.dll’ file is distributed with the program. It is with all of the other required dlls in the same folder as the exe file.

Here is the output from Fuslogvw

*** Assembly Binder Log Entry  (1/14/2010 @ 6:36:51 PM) ***

    Verify that the ‘Microsoft.mshtml.dll’ file, distributed with the program is the PIA file and not an Office file. Some sites claims that the Office files are “delay signed” and the PIA file (installed with the VS installation) is a signed copy. on my computer I have 3 different versions of ‘Microsoft.mshtml.dll’ file, (same file-size, but different content):

    1. “c:\Program Files\Microsoft Visual Studio 9.0\Visual Studio Tools for Office\PIA\Office11\Microsoft.mshtml.dll”

    2. “c:\Program Files\Microsoft Visual Studio 9.0\Visual Studio Tools for Office\PIA\Office12\Microsoft.mshtml.dll”

    3. “c:\Program Files\Microsoft.NET\Primary Interop Assemblies\Microsoft.mshtml.dll”

    Remove “Microsoft.mshtml.dll” reference from the project.
    Use “Add Reference”, “.Net” tab, select the PIA file, use “copy loacal” option.
    (It worked for me . . .)
