Hello there guys...
The issue in short is that I created a Word VSTO addin that works perfectly fine on a number of machines, but fails to load on one machine only. I don't know if the problem is in the assembly name, or there is a missing DLL.
The details of how that is done and the error message are as follows:
1- IDE: Microsoft Visual Studio Community 2013.
2- Office version installed: 2010 for all the machines
3- .NET framework used: 4.0.
4- The target machines have the file vstor_redist.exe installed.
5- The way the VSTO file is installed is through copying the VSTO into program files, then running it. This works for all the machines even the ones that fails to load the add in.
6- The Addin has a ribbon control. Don't know if that has any effect on the matter.
7- Development machine: windows 7 64bit
8- Testing machines: windows 7 64bit. (even the one that fails to load the addin)
9- The error message I am getting when the assembly loads for one machine only is:
Could not load file or assembly 'IDMSWord2010AddinProject, Version=4.3.0.0, Culture=neutral, PublicKeyToken=83105d2b5774c812' or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)
