When installing latest update from Microsoft .NET framework version 4.5.1, leadtools components of version 16.5.0.0 give error message:

You will not be able to use LEADTOOLS v16.5 DLLs with Microsoft .NET framework version 4.5.1, because the version of these DLLs is .NET 2.0. If you want to use v16.5 DLLs with VS 2010, 2012 or 2013, you need to set the application's .NET framework to 2, 3 or 3.5.
Note that the latest version of LEADTOOLS (v18) contains .NET 2.0 and .NET 4.0 DLLs. You should be able to the use the .NET 4.0 DLLs with Microsoft .NET framework version 4.5.1.
If you would like, you can download and try the free evaluation version of LEADTOOLS v18 from our website leadtools.com.

In case someone is searching for BadImageFormatException and comes across this post, I recently posted an article on our blog about the BadImageFormatException that explains what to look for when trying to solve this problem.
