After painful hours of effort, I found a straight-forward solution. Since I am effectively a teen-age driver with this stuff, I hope this gets to you and you can post it properly so the many others that I discovered having the same problem can reduce their search time.
First, I removed as much of the Autodesk files I had on my computer (not an easy task). Then I went to http:\\www.autodesk.com. As you scroll down the main page, there is a icon for DWG Viewer. Install this version first. This installs the 2015 x64 version. When installed, open a dwg file. Go to publish the file to pdf. When you do this, a dialog box pops up and offers a link to open DWF viewer. Accept it. This will take you to the Design Review 2013 site. If you install from the Autodesk website (just run rather than save), it should properly download TrueView 2013. It did for me. I now have DWG True View 2015, DWG True View 2013 and Design Review 2013 icons on my desktop. They all seem to work. (NOTE: I believe you need the current 2015 version to make Design Review work properly.)
By the way, I opened a few files to play around. They opened. But, this newer version of Design Review is not nearly as good or as easy to use as the former Voloview application. I am a real estate consultant. I merely want to open floor plan layouts and building plans from my architects, read the configurations and dimensions and make some simple red-line comments and notes in those files. If Autodesk wants to provide free (or cheap) applications for guys like me, they should make it simple, easy and effective.
Please cause this to get to properly transmitted....if in fact it works for you. Also, please cause this to get to someone of influence at Autodesk. Guys like me would be willing to pay for a simple application that does not require an engineering degree to operate.
