It appears that, although Reader 10.1.3 was installed without incident, there actually are problems with it.
When I tried to print an online PDF, the dialogue box showed a blank page. If I tried a "Save As", a dialogue box said it can't be done. I tried both actions at a few sites and the results were consistent. As well, I tried with FireFox (I use Safari) and it was no better.
I went to the Adobe site and, while they had various suggestions, none generated a positive result. I finally reverted to 10.1.2 and things were back to normal.
Note: In reverting I found that 10.1.3 had two plug-ins where 10.12 only had one. In my first attempt I didn't properly change the plug-ins and had problems.
When you go to Hard Drive/Library/Internet Plug-Ins, after the 10.1.3 upgrade, you will find that there is a 10.1.3 AdobePDFViewer plug-in as well as another called AdobePDFViewerNPAPI.
As well as changing back to 10.1.2 AdobePDFViewer plug-in, I found I also had to remove the AdobePDFViewerNPAPI.
