"Could not parse configuration file..." when I add EF6 to a solution

I get an error when I add EF6 to a solution. I think it also happens when I update the model from the database. The error shows up in the Output window right after I add EF: "Could not parse the configuration file. The error message is: 'Library not registered. (Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED))' Try editing the file manually and then saving it."

The "error" doesn't seem to have any influence on the compiling or running of the application (or the function of EF). However, an error like this is always disturbing when it's with the technology that is supposed to be the linchpin of your data management strategy.

I believe that I have discovered the problem. I can repro it on my development machine and a couple of other dev machines.

I am using VS 2013. The solution that I was using included a second project, a setup/deployment project, InstallShield Limited Edition Project. If I remove that project, the errors go away.

If I create a new project, add EF via Nuget, add an EF model to the solution and then add this setup project I can repro the error. If you try it yourself, just remember you need to open VS and the solution, open the model in the designer, click anywhere in the whitespace of the design surface, the error should pop up in the Output. The details are up there in an earlier post.
