I am a student with proper access to download a SEK version of SolidWorks 2016-2017.

When I'm to the point where I hit install in the installation manager, I get an error message saying that the files I downloaded are missing the "swdata99.id or swdata1.id files needed to identify the version" or it says "the file could not be written".  Looking at the files I unzipped, it's true that neither of those .id files are present.

Any help on this would be great. Thanks.
