Hi,

I have created an add In using VS2013 with targeted framework 4.5. Its working fine in Outlook 2013 (System spec: Windows 8.1, Visual studio 2013 and office 2013).

But when I try to use the same in Outlook 2010 I am getting an error message "The common language runtime could not be loaded by (add in path). Contact your administrator for further assistance.". I have installed required .net framework and Microsoft visual studio 2010 tools for office runtime (Testing machine with windows 7 and office 2010).

The current .NET security policy does not permit <assembly> to run from the folder <path>. Do not change the security policy in your computer. The .NET security policy is controlled by your administrator or the developer who wrote the custom Code


or

The version of the Microsoft .NET Framework on the end user's computer must be the same as or older than the version on the computer that was used to develop the solution. For more information about how to install the .NET Framework and the common language runtime

install .NetFramework 4.0 and try again.

You should try to create the AddIn in VS2010 then to use it in both cases, because the older version should work in the new versions.
