Copy all 33 .dll files from the downloaded plugin lib folder to C:\inetpub\wwwroot and make sure that all of them have permissions for the IIS user.

    Recently had this error 500 with the IIS WebLogic plugin myself and having followed this, the error still occurred.

    The problem turned out to be files such as msvcr110.dll, msvcp110.dll were missing and the 12c plugin at least requires these. This was solved by installing the Visual C++ Redistributable for Visual Studio 2012 – available at https://www.microsoft.com/en-us/download/details.aspx?id=30679#

    After installing, killing the w3wp.exe process and relaunching the website, the 500 error finally went away.
